A method (and system) for generating an output file from a source file where benign modifications to a content of the output file still render the output file authentic, includes constructing an index vector from the source file, quantizing the source file, generating an authentication mark from the quantized source file and the index vector, generating an authentication tag by appending the index vector to the authentication mark, and generating the output file by appending the authentication tag to the source file.

A system accesses a log of events on more than one computing system and scans these logs in an effort to determine the likely cause of various items of interest, events, or problems. These items of interest often include improper or frustrating behavior of a computer system, but may also include delightful or beneficial behaviors for which a user, group of users, company, service, or help desk seeks a cause. Once the likely source of the item of interest is found, a test may be performed to confirm the source of the problem and warning or corrective action taken.

The present invention relates to a method, a system and a computer-readable medium storing computer-executable components in connection with transfer of information data to a recipient. The invention is based on the idea that generation of random number data and the calculation of digital signatures are performed before information data is accessible to a digital pen. Since asymmetric encryption of data is a demanding operation for said digital pen to perform in terms of processing power, a lot of time can be saved if the generation of random number data and asymmetric encryption of said random number data is performed in advance, when the pen is in an idle, non-communicating mode, for example during battery loading of the pen or when the pen is lifted from the position-coded paper. This alleviates delay times when the pen is in its communicating mode.

A band-powered speargun has a release mechanism incorporating a line-drop feature for releasing a coiled line attached to a spear. An approach to attaching the line to the spear involves a linking ring having a size selected so that the ring passes over a protective cone near the spear tip and is captured by an element protruding outward from the spear shaft. The protective cone also shields hinged barbs from impact damage. The gun may also incorporate a muzzle kill spike and a separate hand-held kill spike that is normally stored in a specially designed cavity in the speargun grip.

A method for increasing the expected return of a game, such as a lottery, comprises selling tokens that have a residual value. The price of the tokens is divided between a prize pool and an investment fund. The game is played and the prizes are awarded from the prize pool. Assets are purchased with the investment fund such that the overall expected return of the game over a given period of time is positive. A commitment is made to provide the cash value of the assets to the owners of the tokens at the end of the period of time.

The invention relates to a file management method. TH method comprises the following steps that file taking and putting applications of different storage areas are examines by a server; the storage areas are coded, and light conduction states of the storage areas are displayed on a management screen according to a coding array; and when the light conduction state of any storage area changes, whether the file taking and putting application of the storage area is approved is determined, if yes, recording is carried out, and otherwise, alarm information is emitted. According to the file management method, traditional file management is combined with modern computer technology, paper files are hard to find and tend to be messy are solved, whether files are taken from or put into the storage areas is determined automatically, file taking and removing is timely recorded, and alarm is raised when abnormity occurs; a computer can be used to effectively manage the privilege, an officer cannot take or put the files unless the file taking and putting application is approved by a manager, thereby avoiding the files from loss or misplacement; and the method is especially suitable for management of property files.

The platform device has a user command processing part configured to: receive, from the user terminal, a search request including supplementary information of the sensor terminal as a search condition; in accordance with the search request, search a database in which supplementary information of the sensor terminals, sensing data sensed by the sensor terminals, and identification information of the sensor terminals are associated and stored; and output a search result to the user terminal.

The present invention is intended to provide an anchor that makes it possible to check the placement condition of the anchor easily to realize efficient and safe check after the placement. An anchor includes an expansion member that permits a shaft part to pass therethrough while being placed between a base portion of an anchor bolt and a spreading sleeve. The expansion member includes wing-like expansion parts that are caused to expand by pressing force exerted in the axial direction of the shaft part. The anchor bolt causes the shaft part to rotate in response to the rotation of the base portion of the anchor bolt, thereby driving a cone nut into the spreading sleeve. As a result, spreading parts spread outwardly. Further, the base portion of the anchor bolt presses the expansion member in response to threaded insertion of the shaft part to cause the wing-like expansion parts to expand.
