Copy protection for secured files

Abstract

Embodiments of the present disclosure relate to copy protection. A request to copy a file from a requestor with one or more privileges sufficient to access the file may be received. The file may be determined to be subject to copy protection. In response to determining that the file is subject to copy protection, a notification of the copy attempt may be transmitted. Copy protection may then be applied to the file.

What is claimed is: 
     
         1 . A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method for protecting unauthorized copying of secured files, the method comprising:
 receiving, by a processor, a request to copy a file from a requestor with one or more privileges sufficient to access the file;   determining that the file contains a plurality of hashes, wherein determining that the file contains the plurality of hashes further comprises:
 identifying a plurality of data sets corresponding to the plurality of hashes in the file; 
 determining a number of bits in each data set of the plurality of data sets; 
 comparing the number of bits in each data set to each other; and 
 determining, in response to the number of bits being identical in each data set, that the file contains the plurality of hashes; 
   transmitting, in response to determining that the file contains the plurality of hashes, a notification of the copy attempt;   applying copy protection to the file, wherein applying copy protection to the file comprises:
 generating a dummy version of each hash of the plurality of hashes, wherein generating the dummy versions of each hash comprises: 
 transferring at least one bit from each hash of the plurality of hashes to another hash of the plurality of hashes while maintaining a constant bit-length for each hash; and 
 randomly repositioning bits within each hash after said transferring of each of the at least one bit to another hash; 
   transmitting the file containing the dummy version of each said hash to the requestor; and   transmitting, in response to transmitting the file containing the dummy version of each hash to the requestor, a notification to the requestor that the request to copy the file was successfully processed;   determining requestor information, wherein determining requestor information includes identifying an IP address and account identifier associated with the requestor; and   restricting the requestor's access based on the identified IP address and account identifier.
