    Abstract: Protection of documents printed in paper is provided by processes for detection, immediately and clearly, of different types of falsification, adulteration, inclusion and omission. A network accessible system is capable of detecting several fraud aspects. A “Remote Expertise Center” or a remote service data center accessible from and to any location in which there is a connection to the network, such as through the Internet provides customized protection and automatic verification of document pages. Documents pages are generated by the Remote Expertise Center and transmitted to remote printers, bypassing user operational system, using a specific driver of each printer, avoiding any access to protected document before effective printing. Documents include multiple types of security features, such that in the event that any of them is surpassed, the document will remain protected by the other types of security protection.

    Abstract: A public key cryptography (PKI or other similar system) is used to sent partial or multiple of encryption or decryption algorithm (cipher or decipher) to the data sender or receiver to encrypt or decrypt the data to be sent or received and destroy itself after each or multiple use. Since the encryption algorithm is protected, it can be devised very small in size in compare to the data to be sent and the user can afford to use large key size in it's transmission to increase protection without significant compact to the overall speed. Without knowing the encryption algorithm, which may also be changing from time to time, it will be impossible to use brut force to break the code provided that the algorithm scheme is designed properly. It is due to that there are unlimited numbers of new or old algorithms with countless variations and it takes years of supper fast computing time to break even few algorithms.

  • Publication number: 20110026708
    Abstract: There is disclosed a method for generating data for a recording medium. The method includes receiving original content data representing a plurality of still images and identifying a first subset of the still images to be recorded with copy-protection and a second subset of the still images to be recorded without copy-protection. The method also includes converting data representing the first subset into moving image data and copy-protecting the moving image data. The method also includes generating new content data, the new content data including the copy-protected moving image data and data representing the second subset.

  • Publication number: 20100250940
    Abstract: A data processor is configured to perform wireless communication with a relay transmitter, store a first physical address for the relay transmitter on a storage unit, receive a second physical address for the relay transmitter from the relay transmitter after the data processor being turned on, determine whether the second physical address for the relay transmitter is identical to the first physical address for the relay transmitter, and, when one or more authentication requirements is satisfied, establish wireless connection with the relay transmitter so as to achieve the data communication with an external device via the wireless communication with the relay transmitter. The authentication requirement includes the determination that the second physical address for the relay transmitter is identical to the first physical address for the relay transmitter.

  • Patent number: 7724918
    Abstract: A data obfuscation method, apparatus and computer program product are disclosed in which at least selected text entities such as words or abbreviations in a document are obfuscated to prevent the disclosure of private information if the document is disclosed. A user establishes various configuration parameters for selected text entities desired to obfuscated. The document is processed and text entities matching the configuration parameters are tagged for obfuscation. The tagged entities are then substituted in the document with obfuscating text. The obfuscating text can be derived from a hash table. The hash table may be used to provide a reverse obfuscation method by which original data can be restored to an obfuscated document.

  • Publication number: 20100111301
    Abstract: Protection of documents printed in paper is provided by processes for detection, immediately and clearly, of different types of falsification, adulteration, inclusion and omission. A network accessible system is capable of detecting several fraud aspects. A “Remote Expertise Center” or a remote service data center accessible from and to any location in which there is a connection to the network, such as through the Internet provides customized protection and automatic verification of document pages. Documents pages are generated by the Remote Expertise Center and transmitted to remote printers, bypassing user operational system, using a specific driver of each printer, avoiding any access to protected document before effective printing. Documents include multiple types of security features, such that in the event that any of them is surpassed, the document will remain protected by the other types of security protection.

  • Publication number: 20100086131
    Abstract: A system for remote signature acquisition, includes a local computer located in a first position where a document is needs to be executed, a remote computer located at a second position, a camera connected to the local computer, a tablet connected to the remote computer, and a plotting instrument connected to the local computer. The remote computer is connected to the local computer via a network. The camera presents information of the document to the remote computer via the local computer and network for display at the second position. The tablet records the corresponding input thereon and converts the input to a digital signal which is capable of being transmitted to the local computer via the remote computer and network. The local computer directs the plotting instrument to inscribe the corresponding input on the document according to the digital signal.
