  • Patent number: 5351287
    Abstract: A dialed number recorder, a data monitor, and a personal computer are connected in combination to monitor the data traffic on a suspect "hacker's" telephone line. At the beginning of a call, the dialed number recorder receives and interprets the DTMF signals detected on the line and translates the DTMF signals into the corresponding telephone number dialed. The data monitor receives all signals on the line and converts them into their corresponding characters and transmits these characters, to the personal computer where the characters are stored in a buffer in dynamic memory. The personal computer compares the received data stream against a set of known characters strings looking for a match. If an on-hook signal (indicating the end of the call) is received without a match, the data stored in dynamic memory thus far is erased. If any series of sequential characters matches one of the known strings, the buffered data is written to the computer's disk.
