    摘要: The present invention relates to an apparatus and method for acquiring data stored in a memory of a terminal. Binary data is converted to a new case file and the case file is stored. When meaningful data is extracted, a copy of the case file is generated and the integrity of the copied case file is checked. Then, meaningful data is extracted. A report is generated to correspond to the analyzed meaningful data and is output to a printer and a monitor. Therefore, according to the present invention, all of the data stored in the memory of the terminal are acquired and are converted into the case file in a new format, thereby generating legitimate evidence material for a legal investigation in respect to a legal aspect to be used by investigators.

    摘要: Disclosed is an apparatus and a method of calculating the square root of an element a, which is not zero, belonging to a finite extension field FpAk (where p is a prime number satisfying p≡3(mod 4) and k is an odd number). The method includes: calculating a common exponentiation formula that is common to an exponentiation formula for calculating a quadratic residue, which is used to determine whether the square root of the element a is present, and an exponentiation formula for calculating the square root of the element a when it is determined that the square root of the element a is present; determining the result obtained by multiplying the square of the common exponentiation formula by the element a as the quadratic residue; and determining the result obtained by multiplying the common exponentiation formula by the element a as the square root of the element a.

    摘要: Disclosed is a file sharing method and system using encryption and decryption. A client hashes keywords related to files using a symmetric key algorithm, and encodes the hashed keywords. Then, the client encodes the files using the hashed keywords, and uploads to a file sharing server a ciphertext D including an encoded file m and the encoded keywords KW1, . . . , KWn. In order to download a desired file, the client transmits to the file sharing server a query Q derived from the hashed keyword KW related to the desired file. The client receives from the file sharing server a set SD of ciphertexts created from the same keyword as that queried, decodes the keyword, and decodes the file m using the decoded keyword KW.

    摘要: The present invention relates to an apparatus and method that prevents personal information, which is provided from a user to a website when the user joins the website, from being illegally used. The user uses a reliable website where the personal information can be reliably managed and then stores the personal information in the reliable website. When the user provides the personal information to join a website, the user does not provide actual personal information but provides link information that can be used to link with the reliable website where the personal information is stored. The user and the reliable website share secret information to control a link access authority for the personal information.

    摘要: An apparatus and method for biometrics are provided. The apparatus includes a user registration unit, a user authentication unit, and a transform key storing unit. The user registration unit store a second registration template that transforms a first registration template generated from user biological data using a random orthogonal matrix and random vector. The user authentication unit transforms a first authentication template generated from input biological data the random orthogonal matrix and random vector used in the user registration unit, comparing with the second registration template, and thus performs user authentication. The transform key storing unit provides the random orthogonal matrix and the random vector to the user registration unit and the user authentication unit.
