52 results about "Carriage return" patented technology

A carriage return, sometimes known as a cartridge return and often shortened to CR, <CR> or return, is a control character or mechanism used to reset a device's position to the beginning of a line of text. It is closely associated with the line feed and newline concepts, although it can be considered separately in its own right.

Method for preventing source code from decompiling

The invention provides a method for preventing source code from decompiling, which is characterized in that a computer system is provided with a module capable of preventing the source code from decompiling and comprises a code reading submodule, a code analysis submodule, a virtual mingling submodule, a data access submodule and a mingling code generating module, wherein the code reading submodule reads all codes in a file set into a one-dimensional character string digit group; and all codes are analyzed to obtain information of namespace and class. The code analysis submodule performs the following processes on the codes in the file: removing null string, a front and rear blank space and a Tab symbol, carrying out carriage return and line feed, removing debugging information, removing notes and combining inter-line sentences; and ensuring that the code is easy to process by the virtual mingling submodule by the pretreatment that the code reads submodule. The virtual mingling submodule collects data assembly name, attribute and method, which are used as independent mingling units; the mingled assembly name, attribute and method composite class; and the class is combined into the namespace, and the namespace is combined into the composite file.

Text-type attribute-based relational database watermark embedding method

InactiveCN102184243ANo impact on usabilityResistance to modificationDigital data protectionProgram/content distribution protectionRelational databaseSemantics
The invention discloses a text-type attribute-based relational database watermark embedding method, belongs to the technical field of database security, and relates to a text-type attribute-based relational database watermark embedding and extracting method. The method comprises the following steps of: designing a database watermark mechanism for embedding a watermark in a text-type attribute; and realizing the database watermark mechanism. In the method, binary states of a watermark code element are respectively mapped as a carriage return and a line break aiming at the characteristics of the text-type attribute; and the carriage return and the line break are taken as watermark embedded text attribute values. The watermark has no influence on the original appearance, the semantics and the availability of data; and the watermark extraction does not need an original database. The method is suitable for a text-type attribute-containing database, and has no limit to the number of the words of the text-type attribute. The method has immunity to tuple addition, attribute addition and attribute reordering attack, can effectively resist the tuple modification, the tuple deletion and the attribute deletion attack, and can be used for the protection of a relational database.
