Methods and systems for protecting data integrity

A system comprising:

• a memory;
• and
• one or more hardware processors configured to cause:
• obtaining a first communication comprising first content generated by a first user;
• identifying authentication metadata embedded within the first communication, the authentication metadata comprising data associated with the first user;
• obtaining a second communication generated by a second user, the second communication comprising second content and the authentication metadata;
• determining if the authentication metadata from the second communication belongs to the first user by at least processing the authentication metadata from the second communication and the authentication metadata from the first communication;
• parsing the first content of the first communication and the second content of the second communication;
• comparing the first content with the second content in response to determining that the authentication metadata from the second communication belongs to the first user;
• determining that the first content is different than the second content based at least in part on the parsing and the comparing;
• and
• based at least in part on the determining that the first content is different than the second content, sharing, on a social network system, a version of the second communication, the version comprising an alteration notification indicating that information of the second content has been altered.

A computer program product comprising a non-transitory computer-readable medium storing computer-readable program code to be executed by one or more processors, the program code comprising instructions configured to cause:

• obtaining a first communication comprising first content generated by a first user;
• identifying authentication metadata embedded within the first communication, the authentication metadata comprising data associated with the first user;
• obtaining a second communication generated by a second user, the second communication comprising second content and the authentication metadata;
• determining if the authentication metadata from the second communication belongs to the first user by at least processing the authentication metadata from the second communication and the authentication metadata from the first communication;
• parsing the first content of the first communication and the second content of the second communication;
• comparing the first content with the second content in response to determining that the authentication metadata from the second communication belongs to the first user;
• determining that the first content is different than the second content based at least in part on the parsing and the comparing;
• and
• based at least in part on the determining that the first content is different than the second content, sharing, on a social network system, a version of the second communication, the version comprising an alteration notification indicating that information of the second content has been altered.
