IPA IP 2025 Question 32
A question IPA Japan published in 令和7年度 ITパスポート試験 公開問題 問32, translated into English. ITPEC is based on the same exams.
Which of the following is the most appropriate term that represents a technology for recording the activities of an individual, such as the travel history on public transportation, the product search history on websites, and the data posted on SNS and blogs, or the records themselves?
Explanation
Lifelog — a record of a person's daily activities, kept digitally, or the technology for recording it.
Travel history from IC transit cards, product searches and purchases on websites, posts on SNS and blogs, location data from a smartphone and readings from wearable devices are all lifelogs. Collected in large amounts they become big data, which companies analyse for marketing, recommendations and new services; because they reveal a lot about an individual, their use must respect privacy.
Answer (c)
Why not others:
- •(a) Activity — a general word for an action or a unit of work (for example a task in a project schedule), not a term for recorded personal history
- •(b) Transaction — a business exchange, or in a database a unit of processing that must complete as a whole
- •(d) Record keeping — the managing and keeping of records in general, such as an organization's documents, not the recording of an individual's activities
Key rule: Lifelog = the digital record of an individual's life and actions (movements, searches, posts), a typical source of big data.
