Sony patents file format that verifies content creator identity
Sony describes a system that links a user's verified identity to digital files they create. When a user authenticates with a specific device, the system embeds their user information directly into the content file. This allows other systems to check if the person who made the file is a valid, recognized creator.
In the filing’s own words
Information processing with accurate content creator specification is disclosed. In one example, an authentication device associated with a user is authenticated, content information is generated according to an operation of the user, and in a case where the authentication device is authenticated, a content information file storing the content information and user information of the user is generated. Furthermore, by using the user information stored in the content information file, it is verified whether a creator of the content information stored in the content information file is valid.
What exactly they claim (claim 1)
1. An information processing device comprising: a memory storing a program, and at least one processor configured to execute the program to perform operations comprising: authenticating an authentication device associated with a user; generating content information according to an operation of the user; and generating a content information file that stores the content information and user information of the user only when the authentication device is authenticated, wherein the user information is embedded within the content information file as a data field.
