Methods and systems for providing media asset recommendations based on distributed blockchain analysis
Systems and methods are described for providing media recommendation to a user based on analyzing a blockchain ledger. A user interest score that represents interest of the user in media assets associated with a first keyword is stored. A blockchain ledger is accessed. The blockchain ledger includes multiple blocks, each block identifying: (1) a media asset; (2) a seller user; and (3) buyer user. A blockchain ledger is searched to find a block that: (1) identifies a first media asset that comprises metadata which includes the first keyword; and (2) identifies the user as the seller. The user interest score is then reduced based on such a block being found. A media asset recommendation is then provided to the user based on the user interest score.
1. A method for providing media recommendations to a potential user based on analyzing a blockchain ledger, the method comprising:
storing a potential user interest score that represents interest of the potential user in a media asset associated with a first genre keyword;
searching the blockchain ledger that comprises a plurality of blocks, wherein each block comprises:
an identifier of the media asset;
an identifier of a genre keyword of the media asset;
a cryptographic key for decrypting the media asset for consumption;
data indicating a seller user of an authorization to access the media asset, wherein the block is configured to disallow access to the cryptographic key stored in the block to the seller user; and
data indicating a buyer user of the authorization to access the media asset, wherein the block is configured to allow access to the cryptographic key stored in the block to the buyer user;
wherein the searching the blockchain ledger comprises identifying a first block that comprises:
an identifier of a first media asset and metadata for the first media asset, which includes the first genre keyword;
a first cryptographic key for decrypting the first media asset; and
an indication that an authorization to access the first cryptographic key for decrypting the first media asset was transferred away from the potential user to a buyer user, wherein the potential user no longer has access to the first cryptographic key stored in the first block;
in response to identifying the first block and determining that the first block comprises the indication that the authorization to access the first cryptographic key for decrypting the first media asset was transferred away from the potential user:

8. The method of claim 1 , further comprising:
searching the blockchain ledger to identify a second block, wherein the second block:
identifies a second media asset that comprises metadata that includes a second keyword related to the first keyword; and
identifies the potential user as one of a seller user or a buyer user of an authorization to access the second media asset; and
in response to identifying the second block, modifying the potential user interest score based on whether the second block identifies the potential user as the seller user of the authorization to access the second media asset or as the buyer user of the authorization to access the second media asset.
9. The method of claim 1 , wherein the first block comprises a timestamp indicative of a time when the authorization to access the first media asset was transferred to the potential user.
10. The method of claim 9 , further comprising:
determining a time indicative of when the potential user watched the first media asset;
determining a difference time value between the time identified by the timestamp and the time indicative of when the potential user watched the first media asset;

in response to determining that the difference time value does not exceed the threshold, modifying the potential user interest score by a first amount; and
in response to determining that the difference time value exceeds the threshold, modifying the potential user interest score by a second amount.
