解説
問 61
Incorrectア
Single sign-on (SSO) is an authentication mechanism that lets you use multiple systems or services with a single authentication, without additional re-authentication. It is about convenience and security management, not a technique for combining multiple web services to create new content.
Incorrectイ
Digital forensics is a technology that, when incidents such as unauthorized access or information leakage occur, collects and analyzes logs and data to preserve and investigate legal evidence. It belongs to the field of security incident response and has nothing to do with content-creation techniques.
Incorrectウ
A token refers to a device that generates one-time passwords used to verify a person’s identity during authentication, or a unit of authority or data passed along in communication or processing, and the like. It is not a concept for combining web services to create new content.
- エ
正解 The correct answer is エ, “Mashup.” A mashup is a technique that combines multiple publicly available web services or web pages (maps, weather, social networks, and so on) through Web APIs to create a single new piece of content or service. The example in the question, “embedding and displaying map information provided by another company’s service within a university campus guide page,” takes in the functions of an external service and combines them with one’s own content, making it a typical example of a mashup.
ここがポイント
- Mashup = a technique that combines multiple publicly available web services/web pages (mainly through Web APIs) to create a single new piece of content or service. Embedding a map is a representative example.
- Distinguishing from confusable terms: single sign-on = using multiple services with a single authentication (authentication), digital forensics = evidence preservation and investigation (security), token = a unit of authentication/authority. None of these is a content-combining technique.
