Systems, methods and programs for detecting unauthorized use of text based communications services

摘要

Systems, methods, and programs for generating an authorized profile for a text communication device or account, may sample a text communication generated by the text communication device or account during communication and may store the text sample. The systems, methods, and programs may extract a language pattern from the stored text sample and may create an authorized profile based on the language pattern. Systems, methods, and programs for detecting unauthorized use of a text communication device or account may sample a text communication generated by the device or account during communication, may extract a language pattern from the audio sample, and may compare extracted language pattern of the sample with an authorized user profile.

1. A method for detecting unauthorized user account communications, comprising:
sampling portions of messages, sent from a user account, associated with a first authorized user to obtain a first plurality of message samples; creating a first authorized profile based on first respective language patterns extracted from the first plurality of message samples; determining the first authorized profile is sufficient for identifying unauthorized user account communications; sampling a portion of a recent message sent from the user account to obtain a recent message sample; extracting a language pattern from the recent message sample; and comparing the language pattern extracted from the recent message sample to the first authorized profile according to an allowable amount of deviation between the language pattern extracted from the recent message sample and the first authorized profile to determine whether the recent message is an unauthorized user account communication, the allowable amount of deviation based on an amount of message samples in the first plurality of message samples.
