摘要： Disclosed are a method of inserting vector information for estimating voice data in a key re-synchronization period, a method of transmitting vector information, and a method of estimating voice data in a key re-synchronization period using vector information, capable of estimating the voice data that corresponds to a silent period occurring in a key re-synchronization process when an encrypted digital voice is transmitted in a unidirectional wireless communication environment. A transmitter side inserts accumulation information (i.e., vector information) of a voice change direction of the transmitted previous frame in a key re-synchronization frame, using a voice feature that draws a sine wave, when making the key re-synchronization frame for the re-synchronization, and transmits the key re-synchronization frame with the vector information inserted thereto. A receiver side estimates the voice data value in the key re-synchronization period using the accumulation information (i.e., vector information) in the voice change direction and slopes of the received voice data, to minimize the difference between the original voice and the estimated voice.

摘要： An individual information protecting card is formed by multiple image frequency transformation of the invention is a system utilizing a simplicity of bar cade and an image property of hologram in complexity which is a frequency card being simple in construction. Data to be recorded to the protecting card utilizes an image-based system different from existing numeric cipher code-based system. The image to be used can use not only use a binary image for letters, but also can use continuous grey level as photograph. However, the difference is not in the frequency card exposed externally. Accordingly, expansion to image protecting form is possible and application to a system for managing an information by allocating special image information by individual and by article list is possible. Output of card construction system is made by a reading card possessed by a system operator, a resolution card for increasing of resolution, and user's card being a protecting card. Since the image restoring signal is not produced only by the user's card alone, the image can not be restored from exterior. The image can be restored and seen only when limiting a case inputting a reading card to a key signal. The image can not be restored by a reading card constructed by other image in this case as well. When the resolution card is utilized in response to the case, desired resolution can be obtained.
