Abstract: Systems and methods safeguarding online chat privacy via Uncode keywords encoding that are likely to carry the intent of messages within a conversation between two or more parties. Input of a set of keywords is obtained in chronological order from a conversation between two or more parties for the computing of hash values based on a word's influence on subsequent words in the conversation, and generating a ranked order of the keywords from highest to lowest hash value corresponding to keywords that are likely to carry intent of a conversation. Automatic deletion of messages on each participating devices after every transaction enhances privacy and security. A different Unicode cipher table can be used for each message, device, group, or user, where homomorphic encryption is used for protection of the Unicode cipher table by not exposing encryption keys in unencrypted states when sharing among devices.
