A sending server that sends an agent and a receiving server that receives the agent share a common key. The sending server double-encrypts an agent processing module and transfers to the receiving server an agent storage container that contains the agent processing module, an agent processing module decryption processing program, a receiving server authentication processing program, authentication object information, and a public key. The agent and the receiving server authenticate each other in the receiving server.

Authentication method in an agent system

A plurality of information sources are arranged on a network. An agent program is self-transferred to access the plurality of information sources for executing an information acquiring process. An information service is connected with the network to store an access condition to the plurality of information sources. An agent program is transferred to one of the plurality of information sources according to the access condition necessary for acquiring the information, when the agent program is inputted to the information service , and begins the information acquiring process to acquire the information.

An audio signal is compressed and decompressed. The audio signal is sampled per regular sampling interval to obtain sampled values. The sampled values are orthogonal-transformed per constant period to obtain sequential orthogonal transfer functions. Feature points are extracted that represent change in coefficient intensity of the orthogonal transfer functions per constant frequency interval. Coefficient intensity data, frequency data, and time data of the feature points are obtained. The orthogonal transfer functions are reproduced by interpolating the coefficient intensity of the orthogonal transfer functions on the basis of the coefficient intensity data, frequency data, and time data. The reproduced orthogonal transfer functions are inverse orthogonal-transformed to reproduce the sampled values. And, the reproduced sampled values are converted into the audio signal.

Audio signal compression and decompression utilizing amplitude,

In response to a 'PAUSE RELEASE' command, a CD drive 1 resumes a playback operation earlier than the 'PAUSE' position. The control module 2 analyzes whether continuity is recognized in the time information between a newly entered instruction and a finally processed instruction memorized in the memory 7. Graphic processing and development processing are canceled until the continuity is found. The image data developed in an internal memory 8 is transferred to an external memory 10 through a format conversion module 9. The control module 2 cancels a processing of the newly entered instruction when the newly entered instruction is either Soft Scroll Screen with Preset instruction or Soft Scroll Screen with Copy instruction having a scroll dot number smaller than a predetermined number. Alternatively, all the dot units scroll can be canceled while only the character units scroll can be performed.

A signal coding system capable of high efficiency, high quality signal coding is provided. Digital signals represented in the time domain are divided into set time interval data units and output. One output is converted to a digital signal represented in the frequency domain, and the other is output as-is. The energy dispersion of the digital signal represented in the frequency domain is compared with that of the digital signal represented in the time domain, and the digital signal having the least energy dispersion is coded. This coded digital signal is then multiplexed with an identification signal to identify it as a frequency domain or time domain signal, and the resulting multiplexed signal is output.
