摘要： The invention is especially intended for visually impaired persons who are not able to read text printed on products or product containers. With the invented method at least a part of a product description, which corresponds to a bar code read and which is fetched from a product information database, is stored in at least one memory accessible to the terminal. After this, in response to a command ordered by a user of the terminal, the RFID identifier attached to the terminal is read and the product description is presented in speech format so that the information readable in the memory and the RFID identifier is utilized in the presentation. The terminal is preferably a mobile station equipped with a speech synthesizer. A visually impaired person can point with the terminal to one or more products and listen via an audio system of the terminal to the product descriptions related to them. When RFID identifiers are attached to the product, the products need to be pointed to as precisely when reading bar codes. The products are, for example, foodstuff or medicine.

摘要： A Method and a terminal intended for securing information in a local memory device which is couplable to a terminal having a data link interface. At the terminal, the method comprises the following steps. The method divides 801 original data included in the information to be secured, a division of the original data resulting in a first portion and a second portion. The method stores 802 the first portion in the local memory device and sends 803 the second portion via the data link interface for storage in a remote memory device. The method includes obtaining 804 an authorized read request targeted to the original data and responsive to the authorized read request reconstructs the original data. In more detail, the method retrieves 805 via the data link interface the second portion and combines 806 the second portion and the first portion which was stored in the local memory device. The method provides very high data security if the data, from which the second portion is removed, is encrypted prior to the step of dividing 801. Another aspect of the invention comprises a terminal capable of at least combing the first and second data portions to reconstruct the original data, and preferably to perform the step required for dividing the data. The data may or may not be encrypted.

摘要： The invention represents a method for creating a ciphertext block from a plaintext block consisting of more than one consecutive plaintext character strings (M1, M2, . . . Mn), which are encrypted with an encryption block operating on counter mode. When encrypting a plaintext character string (M3, for example) a hash is formed from the preceding plaintext character string (M2). Preferably the hash is message authentication code MAC or CMAC, the generation algorithm of which uses as a key (Key2) the hash value formed from the plaintext character string (M1) preceding string M2. The hash formed from the plaintext character string (M2) is Counter input to encryption block (Ek) that outputs a key stream (Keystream 3). It is combined in XOR operation with the plaintext character string (M3) wherein the result is a cipher text character string (C3). The invention makes it possible to truncate a file size without losing information stored in the rest of the file.
