개인 정보 보호 샌드박스 용어집

개인 정보 보호 샌드박스 도움말 및 문서는 개인 정보 보호, 광고, 웹 개발의 개념에 대한 지식을 전제로 합니다. 이 용어집에서는 개인 정보 보호 샌드박스와 관련된 주요 용어를 설명합니다.

광고 입찰 (Protected Audience API)

In the Protected Audience API, an ad auction is run by a seller (likely to be an SSP or maybe the publisher itself), in JavaScript code in the browser on the user's device, to sell ad space on a site that displays ads.

광고 소재

Ad creative refers to the contents of the ad served to users. Creatives can be images, videos, audio, and other formats. Creatives live within an ad space, and are served by ad tech within line items.

Ad Exchange

An ad exchange is a platform to automate buying and selling of ad inventory from multiple ad networks.

광고 인벤토리, 광고 공간

광고 인벤토리 공간은 광고 공간을 판매하는 사이트에서 광고를 게재할 수 있는 공간입니다.

광고 플랫폼 (광고 기술)

An ad platform is a company that provides services to deliver ads.

광고주

광고주는 제품 광고에 대한 대가를 지불하는 회사입니다.

집계 가능한 보고서 회계

할당된 개인 정보 보호 예산을 추적하고 '중복 없음' 규칙을 적용하는 두 코디네이터에 모두 있는 분산 원장입니다. 이는 개인 정보 보호 메커니즘으로, 조정자 내에 위치하고 실행되며 할당된 개인 정보 보호 예산을 초과하는 보고서가 집계 서비스를 통과하지 않도록 합니다.

일괄 처리 전략이 집계 가능한 보고서와 어떤 관련이 있는지 자세히 알아보기

집계 가능한 보고서 회계 예산

References to the budget that ensures individual reports are not processed more than once.

집계 가능한 보고서

Aggregatable reports are encrypted reports sent from individual user devices. These reports contain data about cross-site user behavior and conversions. Conversions (sometimes called attribution trigger events) and associated metrics are defined by the advertiser or ad tech. Each report is encrypted to prevent various parties from accessing the underlying data.

Learn more about aggregatable reports.

집계 서비스

An ad tech-operated service that processes aggregatable reports to create a summary report.

Read more about the Aggregation Service backstory in our explainer and the full terms list.

API 호출자

API 호출자는 Topics API에 사용자의 관심분야에 액세스하도록 요청하는 앱, 서드 파티 SDK, 웹사이트와 같은 항목입니다.

증명

일반적으로 암호화 해시 또는 서명을 사용하여 소프트웨어 ID를 인증하는 메커니즘입니다. 집계 서비스 제안서의 경우 증명은 광고 기술 운영 집계 서비스에서 실행되는 코드를 오픈소스 코드와 일치시킵니다.

증명에 관해 자세히 알아보기

기여 분석

Attribution refers to the identification of user actions that contribute to an outcome.

For example, a correlation of ad clicks or views with conversions.

Blink

Blink is the rendering engine used by Chrome, developed as part of the Chromium project.

수입상

A buyer is a party bidding for ad space in an ad auction, likely to be a DSP, or maybe the advertiser itself. Ad space buyers own and manage interest groups.

Publishers make ad inventory available through marketplaces called ad exchanges, and buyers compete in real time through a DSP for the opportunity to place their advertisement.

Learn about ad space buyers in the Protected Audience API.

Chromium

Chromium is an open-source web browser project. Chrome, Microsoft Edge, Opera and other browsers are based on Chromium.

클릭 후 전환(CTC)

클릭 후 전환은 광고 클릭이 기여한 전환입니다.

클릭률(CTR)

The click-through rate is the ratio of users who click on an ad, having seen it.

See also impression.

참여 결합

Aggregatable reports may contain an arbitrary number of counter increments. For example, a report may contain a count of products that a user has viewed on an advertiser's site. The sum of increments in all aggregatable reports related to a single source event must not exceed a given limit, such as L1=2^16 (65,536).

Learn more in the aggregatable reports explainer.

전환

A conversion is the completion of some desired goal following action by a user.

For example, a conversion may occur with the purchase of a product or sign-up for a newsletter after clicking an ad that links to the advertiser's site.

쿠키

A cookie is a small piece of textual data that websites can store on a user's browser. Cookies can be used by a website to save information associated with a user (or a reference to data stored on the website's backend servers) as the user moves across the web.

For example, an online store can retain shopping cart details even if a user is not logged in, or the site could record the user's browsing activity on their site. See First-party cookie and Third-party cookie.

코디네이터

키 관리 및 집계 가능한 보고서 회계를 담당하는 법인입니다. 조정자는 승인된 집계 서비스 구성의 해시 목록을 유지하고 복호화 키에 대한 액세스를 구성합니다.

대략적인 데이터

Coarse data refers to limited information provided by Attribution Reporting API event-level reports. This is limited to 3 pieces of conversion data for clicks and 1 piece for views. Specific, granular conversion data (such as specific prices of items and timestamps) are not included.

데이터 관리 플랫폼(DMP)

데이터 관리 플랫폼은 광고주와 관련된 데이터를 수집하고 관리하는 데 사용되는 소프트웨어입니다. 이러한 플랫폼을 통해 광고주와 게시자는 잠재고객 세그먼트를 식별한 후 캠페인 타겟팅에 사용할 수 있습니다.

DMP에 대해 자세히 알아보세요.

수요측 플랫폼 (DSP)

A demand-side platform is an ad tech service used to automate ad purchasing. DSPs are used by advertisers to buy ad impressions across a range of publisher sites.

개인 정보 차등 보호

개인 정보 차등 보호란 개인의 개인 정보 또는 개인이 데이터 세트에 속하는지 여부를 드러내지 않고 데이터 세트에 관한 정보를 공유하여 행동 패턴을 확인할 수 있게 하는 기법을 의미합니다.

도메인

도메인. 최상위 도메인 및 eTLD를 참조하세요.

엔트로피

Entropy, in the privacy domain, is a measure of how much an item of data reveals individual identity.

Data entropy is measured in bits. The more that data reveals identity, the higher its entropy value.

Data can be combined to identify an individual, but it can be difficult to work out whether new data adds to entropy. For example, knowing a person is from Australia doesn't reduce entropy if you already know the person is from Kangaroo Island.

세대

In the Topics API, an epoch is the period of time during which the browser infers topics for a user based on their browsing activity. It is currently set to one week.

eTLD, eTLD+1

eTLDs are effective top-level domains (TLD), which are defined by the Public Suffix List.

For example:

co.uk 
github.io 
glitch.me

Effective TLDs are what allow foo.appspot.com to be a different site from bar.appspot.com. The eTLD in this case is appspot.com, and the whole site name (foo.appspot.com, bar.appspot.com) is known as the eTLD+1.

See also Top-Level Domain.

이벤트 수준 보고서

Event-level reports associate a particular ad click or view (on the ad side) with data on the conversion side. To preserve user privacy by limiting the joining of user identity across sites, conversion-side data is very limited, and the data is noisy.

Federated Credential Management API (FedCM)

Federated Credential Management API is a proposal for a privacy-preserving approach to federated identity services. This will allow users to log into sites without sharing their personal information with the identity service or the site.

FedCM was previously known as WebID, and is still in development in the W3C.

제휴 ID (제휴 로그인)

Federated identity is a third-party platform to allow a user to sign in to a website, without requiring the site to implement their own identity service.

분리 프레임

A (<fencedframe>) is a proposed HTML element for embedded content, similar to an iframe. Unlike iframes, a fenced frame restricts communication with its embedding context to allow the frame access to cross-site data without sharing it with the embedding context.

Some Privacy Sandbox APIs may require select documents to render within a fenced frame. Learn more about the Fenced Frames proposal.

디지털 지문 수집

Fingerprinting encompasses techniques to identify and track the behaviour of individual users.

Fingerprinting uses mechanisms that users aren't aware of and can't control.

디지털 지문 수집 표면

A fingerprinting surface is something that can be used (probably in combination with other surfaces) to identify a particular user or device.

For example, the navigator.userAgent() JavaScript method and the User-Agent HTTP request header provide access to a fingerprinting surface (the User-Agent string).

자사

First party refers to resources from the site you're visiting.

For example, the page you're reading is on the site developer.chrome.com and includes resources requested from this site. Requests for those first-party resources are called 'first-party requests'. Cookies from developer.chrome.com stored while you're on this site are called first-party cookies.

See also Third-party.

퍼스트 파티 쿠키

퍼스트 파티 쿠키란 사용자가 사이트에 머무는 동안 웹사이트에 저장된 쿠키입니다.

예를 들어 온라인 상점은 로그인하지 않은 사용자의 장바구니 세부정보를 보관하기 위해 브라우저에 쿠키를 저장하도록 요청할 수 있습니다. 서드 파티 쿠키도 참조하세요.

I2E

Intent to Experiment (I2E) is the announcement of a plan to make a new Blink feature available to users for testing, typically through an origin trial.

I2EE

실험 연장 인텐트 (I2EE)는 오리진 트라이얼 기간을 연장하려는 계획을 발표한 것입니다.

I2P

I2P (Intent to Prototype)는 Blink에서 새로운 기능을 개발하는 첫 번째 단계입니다. 이 공지사항은 토론을 위한 제안 링크와 함께 blink-dev 메일링 리스트에 게시됩니다.

I2S

Intent to Ship (I2S) is an announcement of a plan to make a new feature of Blink available to users in stable versions of Chrome.

노출

Impression could refer to either:

• View of an ad. See also click-through rate.
• An ad slot: the HTML markup (usually <div> tags) on a web page where an ad can be displayed. Ad slots constitute inventory.

관심 기반 광고 (IBA)

Interest-based advertising (IBA) is a form of personalized advertising in which an ad is selected for a user based on their interests, inferred from the user's activity: the sites they've recently visited on the web, or the apps they used on Android. This is different from contextual advertising, which aims to match ads to the content the user is viewing.

관심분야 그룹

In the Protected Audience API, formerly FLEDGE, an interest group represents a group of people with a common interest, corresponding to a remarketing list.

Every interest group has an owner. Different types of owners will create different types of interest groups with different use cases.

인벤토리

Inventory is the ad slots available on a site. Ad slots are the HTML markup (usually <div> tags) where ads can be displayed.

k-익명성

K-anonymity is the measure of anonymity within a data set. If you have k anonymity, you can't be distinguished from k-1 other individuals in the data set. In other words, k individuals have the same information (including you).

노이즈 및 확장

Statistical noise that is added to summary reports during the aggregation process to preserve privacy and ensure the final reports provide anonymized measurement information.

Read more about additive noise mechanism, which is drawn from Laplace distribution.

Nonce

nonce는 암호화 통신에서 한 번만 사용되는 임의의 숫자입니다.

출발지

출처는 출처는 프로토콜 (프로토콜), 호스트 이름 (도메인), 출처에 액세스하는 데 사용된 URL 포트로 정의됩니다.

예: https://developer.chrome.com

오리진 트라이얼

Origin trials are trials that provide access to a new or experimental feature, to make it possible to build functions that users can try out for a limited time before the feature is made available to everyone.

When Chrome offers an origin trial for a feature, an origin can be registered for the trial to allow the feature for all users on that origin, without requiring users to toggle flags or switch to an alternative build of Chrome (though they may need to upgrade). Origin trials allow developers to build demos and prototypes using new features. The trials help Chrome engineers understand how new features are used, and how they may interact with other web technologies.

Find out more: Getting started with Chrome's origin trials.

수동 표면

Passive surfaces are fingerprinting surfaces—such as User-Agent strings, IP addresses, and Accept-Language headers—that are available to every website, whether the site asks for them or not.

Passive surfaces can easily consume a site's privacy budget.

The Privacy Sandbox initiative proposes replacing passive surfaces with active ways to get specific information, for example using Client Hints a single time to get the user's language rather than having an Accept-Language header for every response to every server.

Protected Audience API

Protected Audience API는 FLEDGE API의 새로운 이름입니다.

게시자

In the Privacy Sandbox context, a publisher is a site with ad space that is paid to display ads.

도달범위

실시간 입찰 (RTB)

Real-time bidding refers to an automated auction for buying and selling ad impressions on websites, completed during page load.

리마케팅

Remarketing is the practice of advertising to people who've already visited your site on other sites.

For example, an online store could show ads for a toy sale to people who previously viewed toys on their site.

신고 출처

The entity that receives aggregatable reports—in other words, you or an ad tech that called the Attribution Reporting API. Aggregatable reports are sent from user devices to a well-known URL associated with the reporting origin. The reporting origin is designated during enrollment.

크기 조정 요소

Scaling factor, in the context of the Attribution Reporting API, refers an amount by which you choose to multiply an aggregatable value. Scaling impacts the effect of noise and your contribution budget.

판매자

판매자는 광고 입찰을 실행하는 당사자이며 SSP 또는 게시자일 수 있습니다.

공유 ID

shared_info, reporting_origin, destination_site (Attribution Reporting API만 해당), source_registration-time (Attribution Reporting API만 해당), scheduled_report_time, 버전으로 구성된 계산된 값입니다.

shared_info 필드에서 동일한 속성을 공유하는 여러 보고서는 공유 ID가 동일해야 합니다. 공유 ID는 집계 가능한 보고서 회계에서 중요한 역할을 합니다.

신뢰할 수 있는 서버에 관해 자세히 알아보기

사이트

A site is equivalent to an eTLD+1 along with a scheme (protocol).

See also Top-Level Domain.

스토리지 파티셔닝

Storage partitioning is a mechanism in Chrome to prevent certain types of side-channel cross-site tracking, Chrome is partitioning storage and communications APIs in third-party contexts.

Storage partitioning prevents a site from joining data across different sites to track the user across the web.

요약 보고서

Attribution Reporting API 및 Private Aggregation API 보고서 유형입니다. 요약 보고서에는 집계된 사용자 데이터가 포함되며 노이즈가 추가된 세부 전환 데이터가 포함될 수 있습니다. 요약 보고서는 집계 보고서로 구성됩니다. 특히 전환 가치와 같은 일부 사용 사례의 경우 이벤트 수준 보고보다 더 유연하고 더 풍부한 데이터 모델을 제공합니다.

공급측 플랫폼, 판매측 플랫폼

A supply-side platform is an ad tech service used to automate selling ad inventory. SSPs allow publishers to offer their inventory (empty rectangles where ads will go) to multiple ad exchanges, DSPs, and networks. This enables a wide range of potential buyers to bid for ad space.

Surface

Surface. See Fingerprinting surface and Passive surface.

타사

Third party refers to resources served from a domain that's different from the website you're visiting.

For example, a website foo.com might use analytics code from google-analytics.com (via JavaScript), fonts from use.typekit.net (via a link element) and a video from vimeo.com (in an iframe). See also First-party.

서드 파티 쿠키

A third-party cookie is a cookie stored by a third-party service.

For example, a video website might include a Watch Later button in their embedded player to allow a user to add a video to their wishlist without forcing them to navigate to the video site.

See also First-party cookie.

최상위 도메인 (TLD)

Top-level domains such as .com and .org are listed in the Root Zone Database.

See also eTLD, site.

주제

A topic is a human-readable topic of interest of a user and is part of the Topics taxonomy.

주제 분류

The Topics taxonomy is a public, human-curated, human-readable hierarchy of categories that the Topics API uses to represent users' interests.

신뢰할 수 있는 실행 환경(TEE)

A secure configuration of computer hardware and software that allows external parties to verify the exact versions of software running on the machine without fear of exposure. TEEs allow external parties to verify that the software does exactly what the software manufacturer claims it does—nothing more or less.

To learn more about TEEs used for the Privacy Sandbox proposals, read the Protected Audience API services explainer and the Aggregation Service explainer.

User-Agent 클라이언트 힌트 (UA-CH)

사용자 에이전트 클라이언트 힌트는 명시적 요청에 사용자 에이전트 문자열의 특정 부분을 제공합니다. 이를 통해 사용자 식별 또는 은밀한 추적으로 이어질 수 있는 사용자 에이전트 문자열의 수동 노출 영역을 줄일 수 있습니다.

UA-CH는 '클라이언트 힌트'라고도 합니다.

사용자 에이전트 문자열

A user-agent string is an HTTP header used by servers and network peers to request identifying information about an application, operating system, vendor, or version of a user agent. The User-Agent string broadcasts a large string of data, which is problematic for user privacy. User-Agent reduction is proposed to remove sensitive information and reduce passive fingerprinting.

.well-known

.well-known은 표준 URL에서 웹사이트로 리디렉션을 추가하는 데 사용되는 파일입니다.

예를 들어 비밀번호 관리자를 사용하면 웹사이트가 /.well-known/change-password에서 사이트의 비밀번호 변경 페이지로의 리디렉션을 설정하는 경우 사용자가 비밀번호를 더 쉽게 업데이트할 수 있습니다.

또한 요청하기 전에 호스트에 대한 정책 또는 기타 정보에 액세스하는 것도 유용할 수 있습니다. 예를 들어 robots.txt는 웹 크롤러에 방문할 페이지와 무시할 페이지를 지정합니다. IETF RFC8615는 /.well-known/ 하위 디렉터리의 표준 위치에서 사이트 전체 메타데이터에 액세스할 수 있도록 하는 표준화된 방법을 설명합니다.
