Problems solved by technology

Since these sensitive information are sent in clear text, they are vulnerable to eavesdropping on the communication line, thus endangering the user's information security
On the other hand, many phones (or mobile phone application software) will play the prompt tone when the user presses the key, so if the user enters sensitive information, the attacker records it nearby and decodes it to obtain the information entered by the user. All information, resulting in user information leakage, may bring huge economic losses to users

Embodiment Construction

[0031] In practical applications, it is necessary to encrypt sensitive data such as credit card numbers and ID numbers transmitted over telephone lines. However, using traditional block ciphers (such as AES or 3DES) usually expands the data, changing the length and type of the data. This makes the encrypted data different from the original data in length and type. Due to the limited data types that can be input in the IVR system, the input data that needs to be encrypted for general interactive voice response services are sensitive information such as account numbers, passwords, and PIN codes. , these sensitive information are all composed of decimal integers, and the encrypted result we hope to obtain is in a format that can be input through the telephone keyboard, that is, the output ciphertext is in the format of decimal integers, but if traditional block ciphers (such as AES or 3DES) cannot Meet the needs of interactive voice response systems. Therefore, it is necessary to...

Abstract

The invention discloses an interactive voice response system. The interactive voice response system comprises a server-end device and a client-end device, wherein the server-end device and the client-end device perform interaction through a telephone network, and a user inputs information on the client-end device; the information is encrypted by a format-preserving encryption algorithm, and then the information after encryption is encoded into a DTFM (dual-tone multi-frequency) signal for transmission on the telephone network; and the information is transmitted to a server end and then decrypted by a server end device. According to the technical scheme disclosed by the invention, sensitive data of the interactive voice response system can be encrypted and protected, so that the system can be safe and reliable.

Description

technical field [0001] The invention relates to an interactive voice response system, in particular to an interactive voice response system and method. Background technique [0002] The IVR (Interactive Voice Response) system, that is, the interactive voice response system, is widely used in call centers and is an important portal for call centers to realize human-computer interaction. In a traditional IVR system, the way the user interacts with the system is through the phone's keypad. Usually, after the user enters the IVR system, he will hear the relevant voice prompt menu, and can press the relevant key on the keyboard according to his needs. The system transmits the key pressed by the user through the DTMF (Dual-Tone Multi-Frequency, Dual-Tone Multi-Frequency) signal, and at the same time transmits the user's request to the system, thereby triggering the relevant voice information. Common interactive voice response systems include operations such as balance inquiries,...
