Abstract:
Systems and methods safeguarding online chat privacy via Unicode 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. Further, the method of the present invention includes generating a Unicode cipher table at the first chat device by obtaining an encryption key from the homomorphic key server to encrypt the Unicode cipher table comprises a homomorphic operation on a first table key in combination with a first chat device key and a second chat device key.

Claim (Index 7):
A method as in  claim 1 , wherein the generating in the chat memory a hash value for the Unicode cipher table comprises:\n obtaining an input of a set of keywords in chronological order from a conversation between two or more parties; computing a hash value of each keyword by capturing each keyword's influence on the subsequent keywords in the conversation based on the number of times the keyword subsequently occurs in the conversation, and wherein said computing is carried out by a scoring operation module executing on a hardware processor of a computing device; and generating a ranked order of the keywords from highest to lowest hash value, wherein the highest hash value corresponds to the keyword which is most likely to carry intent of the conversation, and wherein said generating is carried out by a distribution module executing on a hardware processor of the computing device.
