Detecting disclosed content sources using dynamic steganography

A computer program product, embodied in a non-transitory computer readable medium, the non-transitory computer readable medium having stored thereon a sequence of instructions which, when stored in memory and executed by a processor causes the processor to perform a set of acts, the set of acts comprising:

• identifying a rendered view of an object comprising an image, the image having multiple sites where one or more steganographic messages have been placed, wherein the one or more steganographic messages correspond to one or more attributes of a source that have been encoded into the image by modifying pixel data in the image, wherein a particular steganographic message comprises a matrix of squares where a square of the matrix of squares represents a binary value used to modify the pixel data at a given pixel location;
• uploading the rendered view of the object to a server to detect a steganographic message by retrieving object attributes from a security database and using the object attributes to implement at least one of scaling the object or partitioning the object to identify the multiple sites having placement of the one or more steganographic messages within a partition of the object;
• decoding the steganographic message from at least one of the multiple sites that was detected using the at least one of scaling the object or partitioning the object to identify the source;
• and
• extracting user information according to steganographic settings associated with the object.

A system comprising:

• a server in a cloud-based environment, wherein the server is interfaced with one or more storage facilities that store one or more objects accessible by two or more users;
• and
• a processing element that performs:
• identifying a rendered view of an object comprising an image, the image having multiple sites where one or more steganographic messages have been placed, wherein the one or more steganographic messages correspond to one or more attributes of a source that have been encoded into the image by modifying pixel data in the image, wherein a particular steganographic message comprises a matrix of squares where a square of the matrix of squares represents a binary value used to modify the pixel data at a given pixel location;
• uploading the rendered view of the object to a server to detect a steganographic message by retrieving object attributes from a security database and using the object attributes to implement at least one of scaling the object or partitioning the object to identify the multiple sites having placement of the one or more steganographic messages within a partition of the object;
• decoding the steganographic message from at least one of the multiple sites that was detected using the at least one of scaling the object or partitioning the object to identify the source;
• and
• extracting user information according to steganographic settings associated with the object.
