the timer and the counter respectively count the machine period number of the MCU and count an externally input pulse signal;
the interrupt system ensures the processing capacity of the MCU for emergency;
the client hardware is a hardware device comprising a decryption system, when receiving the identification result, the MCU sends the encrypted identification result to the client, the client hardware can be a mobile phone, a tablet or a computer, when the identification result sent to the client hardware by the MCU is displayed on the client hardware, the identification result is still the encrypted identification result, the identification result is decrypted by the decryption system arranged in the client hardware and then can be recorded and stored, and the client hardware carries a dialing sequence which is the same as that of the voice identification chip.
Preferably, the decryption system inside the client hardware comprises a database, and a decryption table is arranged inside the database, and data in the decryption table is derived from the encrypted common pinyin string in the voice recognition chip.
The invention has the following beneficial effects:
1. this automatic voice entry system of text for telephone network carries out MD5 encryption operation immediately through the speech information that finishes with MCU processing, and the condition that has appeared that system intrusion data is stolen can not cause the information leakage even if the in-process of data transmission, because MD5 encryption operation is irreversible, just also can't be complete once more deciphers, and the mode efficiency of cracking and hitting the storehouse is extremely low, can't complete display information content, assurance information security that can maximize.
2. The automatic text voice input system for the telephone network is characterized in that a database is arranged at a client, and a common identification list and an encrypted text of the identification list are stored in the database, so that when the client receives encrypted text information, a ciphertext can be collided with the encrypted text of the identification list in the database for comparison, the efficiency of colliding the database can be ensured, in addition, the dialing sequence of the transmission client can be automatically identified through the arrangement that a voice identification chip and client hardware carry the same dialing sequence, the dialing sequence is not in one-to-one correspondence, decryption operation cannot be carried out, and the information safety can be further ensured.
