摘要： The present invention is a method and apparatus for protection of various items against counterfeiting using physical unclonable features of item microstructure images. The protection is based on the proposed identification and authentication protocols coupled with portable devices. In both cases a special transform is applied to data that provides a unique representation in the secure key-dependent domain of reduced dimensionality that also simultaneously resolves performance-security-complexity and memory storage requirement trade-offs. The enrolled database needed for the identification can be stored in the public domain without any risk to be used by the counterfeiters. Additionally, it can be easily transportable to various portable devices due to its small size. Notably, the proposed transformations are chosen in such a way to guarantee the best possible performance in terms of identification accuracy with respect to the identification in the raw data domain. The authentication protocol is based on the proposed transform jointly with the distributed source coding. Finally, the extensions of the described techniques to the protection of artworks and secure key exchange and extraction are disclosed in the invention.

摘要： A method and apparatus for protection of products and packaging against counterfeiting using dedicated authentication protocol coupled with portable devices. It is based on the product identification information, i.e., PIN, generated by the product manufacturer, stored in the product database and added to product or packaging in an open and/or a hidden form. The open part is directly available to the consumer before buying, opening or consuming the product or package or damaging its integrity while the hidden part is only revealed after these operations. The hidden information can also be disappearing after a predefined interval of time or number of trials or usages. Both parts are communicated to the authentication server in a predefined order to verify the product or package authenticity. The presence, absence, or multiple requests for the same product PIN, confirm or reject product authenticity or detect attempt at attacking the system or using counterfeited products.
摘要翻译：一种使用与便携式设备相结合的专用认证协议来保护产品和打包防伪的方法和装置。它基于存储在产品数据库中并由开放和/或隐藏的形式添加到产品或包装中的由产品制造商产生的产品标识信息，即PIN。开放部分在购买，开放或消费产品或包装之前可直接提供给消费者，或者在这些操作之后才会显示隐藏部分。隐藏的信息也可能在预定义的时间间隔或试验或使用次数后消失。两个部分以预定义的顺序传达给认证服务器，以验证产品或包的真实性。对同一产品PIN的存在，不存在或多次请求，确认或拒绝产品真实性或检测攻击系统或使用假冒产品的尝试。

摘要： The present invention relates to the methods of estimation and recovering of general affine geometrical transformations which were applied to data, extensible to any other defined class of geometrical transformations, according to the preamble of the dependent claims. The parameters of the undergone deformation are robustly estimated based on maxima given by a parametric transform such as Hough transform or Radon transform of some embedded information with periodical or any other known regular structure. The main applications of this invention are robust digital still image/video watermarking, document authentication, and detection of periodical or hidden patterns. In the case of periodical watermarks, the watermark can also be predistorted before embedding based on a key to defeat block-by-block removal attack.

摘要： The present invention is a method and apparatus for watermarking text or vector graphics documents. It is based on character-wise or vector graphics element-wise grayscale or color modulation. At high resolution, halftone or dither modulation can also be used in addition or in place of grayscale/color modulation, for printed representation of electronic document. For the detection, the document is acquired through an acquisition device, document segmentation is performed, characters/elements are segmented, the watermark signal is estimated and the information is decoded. Although the proposed scheme mostly addresses the watermarking of hard-copy documents, it can easily be integrated into electronic document editing and acquisition tools, and the watermark is attached to the document electronic version.The invention is applicable either using expensive high-resolution printing and acquisition devices, either using common cheap low-resolution devices, depending on the application needs. The proposed scheme is suitable for example to the protection of security documents, contracts, technical and commercial documentation; it can use any physical support like paper, cellulose, or plastic; it can be used for copy protection, authentication, or tamper proofing; finally it can also be applied to other non security-related applications, such as document tracking, as well as document embedded annotation and watermarked-assisted automatic processing.
