An approach is provided for deterring a tampering of content. Content is signed by using an asymmetric key cryptography. The signed content is stored in a distributed ledger which is accessible to a plurality of subscribers of the distributed ledger. The signing of the content using the asymmetric key cryptography together with the storing of the signed content in the distributed ledger provide a non-repudiable identification of an owner of the content and a non-repudiable proof of an ownership of the content.

Decentralized repository using encryption for non-repudiable activity and ownership

A computer-implemented method, system and computer program product for improving query searches. After receiving a query from a user to conduct a content search, the query is analyzed for its semantic meaning and a categorized group of query tags and content tags in the central repository that is most semantically similar in meaning to the meaning of the query is identified. Furthermore, the content tags and query tags in the user's repository are analyzed to determine the interests of the user. The query may then be augmented to include one or more other terms of interest from the identified categorized group of query tags and content tags in the central repository that match the determined interests of the user within a threshold degree of relatedness, where these other terms of interest correspond to the content tags and query tags of the identified categorized group based on their assigned weight.
