Abstract: The invention relates to a security element applied onto printing substrates (bank notes, securities, product packagings, identity cards/labels or other similar documents) by printing, comprising a unique identifier as primary information visible to the naked eye and secondary information protecting against copying non-visible to the naked eye. The unique identifier is typically a point code. Said secondary information is represented by a structure with the largest dimension of 2 to 40 microns, and due to printing distortions arising when the security element is applied onto a printing substrate, said secondary information is non-reconstructable from the print of the security element and a statistically analyzable inherent feature is associated to it. The invention also relates to a printed matter with such an inventive security element and to a method to check authenticity of a printed matter with the inventive security element in visible light (380-750 nm).

Abstract: The specification discloses a method of generating and recognizing voice based playback information, and a recording medium for storing instructions for performing the method. That is, a voice playback file for outputting voice is converted to playback information, and the voice is outputted by playing back the voice playback file, when the playback information is recognized. Thus, a recording function, which can be utilized in various fields, can be provided without using a separate storage for storing the voice playback file.

Abstract: A data certification system includes a proof information generation unit that generates certification information for certifying non-falsification of raw data, and generates proof information including the certification information and time information representing the time of the generation of the certification information. A server transmission unit transmits the proof information which is received by a client reception unit. A time information acquisition unit acquires the time information representing the time of the generation of the certification information from the proof information. A report generation unit generates report data in which the time information and publishing destination information representing a publishing destination are included in the raw data. A transfer unit transfers the raw data, the proof information, and the report data to a publishing server which releases the report data. An output unit outputs the report data.

Abstract: The application provides a method for partitioning a watermark image with western language characters, comprising: partitioning a western language characters image along rows and columns to form a plurality of character image blocks; identifying valid character image blocks from the formed character image blocks; counting sizes of the valid character image blocks to determine if the image corresponds to a document with a large font size or a document with a small font size; dividing words in the image into a plurality of groups, wherein each divided group in the document with large font size has different numbers of words from that with small font size; and dividing equally the divided word groups into multiple portions corresponding to watermark image blocks. The application further provides a device for partitioning a watermark image with western language characters. The operability of watermark embedding process can be ensured through the above technical solution.

Abstract: A computer-based method and a system for adding and printing variable security data. The system includes a memory, a processor, and a printer. The memory stores received print data. The processor modifies the print data for adding variable security print data and sends the modified print data for printing. The printer receives and prints the modified print data. The variable security data may vary between different printing operations. The processor captures a portion of the stored print data based on data-capturing criteria and modifies the stored print data based on the captured portion of the stored print data. The data-capturing criteria may be user-defined and may include leading tag data, trailing tag data, matching tag data, or combinations thereof for indicating a relative position of the captured data.

Abstract: It is possible to verify non-falsification of output data without using a device which issues proof information as information for certifying non-falsification. A proof information generation unit generates certification information for certifying non-falsification of raw data, and generates proof information including the certification information and time information representing the time of the generation of the certification information. A server transmission unit transmits the proof information to a client device. A client reception unit receives the proof information transmitted from a server device. A time information acquisition unit acquires the time information representing the time of the generation of the certification information from the proof information. A report generation unit generates report data in which the time information and publishing destination information representing a publishing destination are included in the raw data. A transfer unit transfers the raw data, the proof information, and the report data to a publishing server which releases the report data. An output unit outputs the report data.

Abstract: Character spacing values in a document image are extracted and a variance is calculated for fluctuations in the character spacing values. When the calculated variance is lower than a preset threshold value, the document image is determined as having watermark information embedded therein. Such use of the variance in the character spacing values enables high-speed determination of the presence or absence of character-spacing watermark information. At this time, it is possible to speed up the determination by using only some character spacing values in the document, instead of using all character spacing values.

Abstract: Directional albedo of a particular article, such as an identity card, is measured and stored. When the article is later presented, it can be confirmed to be the same particular article by re-measuring the albedo function, and checking for correspondence against the earlier-stored data. The re-measuring can be performed through us of a handheld optical device, such as a camera-equipped cell phone. The albedo function can serve as random key data in a variety of cryptographic applications. The function can be changed during the life of the article. A variety of other features are also detailed.
