A mobile terminal and application providing method for same are disclosed whereby the method provides a requested application using an application package installer having multiple pieces of signature information. The application providing method comprises: obtaining an application package installer containing multiple pieces of signature information; determining whether signature information corresponding to the mobile terminal is present in the multiple pieces of signature information; and generating, when signature information corresponding to the mobile terminal is present, a signed application package based on the corresponding signature information.

Mobile terminal and application providing method for the same

The present invention relates to a system for implementing a firewall service on portable devices such as mobile phones, tablets or notebooks, which has changed their security settings depending on the location where they are. More specifically, the invention relates to a method of protecting data flow and control of use of devices and functional applications present in a portable device and configured from their location.

System for data flow protection and use control of applications and portable devices configured by location

A variable length encoding/decoding apparatus using symbol-codeword re-association of a variable length code table includes a re-associator for storing symbol-address assignment information, address-codeword assignment information and address-counter-value assignment information, altering the symbol-address assignment information and the address-counter value assignment information according to the varied counter value due to the symbol identifying and outputting a variable length code table in which a symbol-codeword is re-associated to the encoder/decoder apparatus, and a controller for producing the initialized counter values based on probabilities of symbol occurrences belonging to the pre-defined variable length code table and the information stored in the re-associator based on the pre-defined updating unit, and storing the symbol-codeword re-associated variable length code table every predetermined updating unit in the encoder/decoder. A data compression efficiency can be improved even though global statistics corresponding to the pre-defined variable length code table and local statistics of the symbols/codewords which are actually variable-length-encoded/decoded do not match each other. Since it is not necessary to transmit the symbol-codeword re-association information at the encoding end to a decoding end, threre is no additional data to be transmitted by employing the present invention.
