First Claim
1. A storage device which provides a storage area for storing content in accordance with a request from a user and can publish the stored content, comprising:
- an interface;
a processor connected to the interface; and
a memory connected to the processor, whereinthe memory stores user management information including identification information of a user who can access the storage area,the storage area includes publishing content storage area which publishes the stored content to outside, andthe processoraccepts a content storage request from the user,generates duplication identification information for determining duplication of content based on the accepted content,determines whether or not duplicate content of the accepted content is stored in the storage area based on-the generated duplication identification information,embeds a digital watermark including identification information of the user to the accepted content, thereby generating publishing content if the duplicate content of the accepted content is not stored in the storage area,stores the publishing content in the publishing content storage area, anddoes not store the content in the publishing content storage area if the duplicate content of the accepted content is stored in the storage area.
