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 9):
A chat history deletion method useful in safeguarding privacy, the method comprising:\n at an online communication system including a chat server having a chat memory and a plurality of communication devices: sending a first acknowledgement from the chat server to a first communication device after receiving a chat message initiated from the first communication device; determining receiving of the first acknowledgement at the first communication device; in response to determining receiving of the first acknowledgement, the first communication device deletes all traces of the chat message; sending a second acknowledgement from a second communication device to the chat server after receiving of the chat message at the second communication device; determining count of acknowledgements received at the chat server equals to count of communication devices; in response to determining count of acknowledgements received at the chat server equals to count of communication devices, deleting all traces of the chat message from the chat memory of the chat server; and deleting all traces of the chat message from the second communication device after displaying of the chat message on the device.
