摘要： A method of protecting a graphical object (410) represented by a list of vertices and a list of surfaces, each surface being defined by a number N vertices. A device (310) selects (110) a surface S with N vertices; computes (120) a new vertex d using a random or pseudo-random function; inserts (130) the new vertex d into the list of vertices; creates (140) N new surfaces S1-SN from the surface S and the new vertex d; and replaces (150) the selected surface S by the new surfaces S 1- SN in the list of surfaces. The device (310) preferably iterates the method. The device (310) may shuffle the list of vertices with the inserted vertices. Also provided is an unprotection method and corresponding devices and computer readable storage media.

摘要： A main screen (120) renders watermarked content. A remote device (130) captures (402) a watermark and extracts (404) a payload comprising a layout type, displays (412) possible answers according to the layout type and receives (414) a response from a user. The remote device (130) captures (402) a further watermark and extracts (404) a payload comprising a correct answer, a ratio value and a token value. If the correct answer is equal to the answer received from the user, the remote device (130) generates (418) a comparison value, compares (420) the comparison value and a ratio value extracted from the payload and, if the comparison between the comparison value and the ratio value indicates that remote device (130) has been selected, displays (424) a message intended to a user. The remote device (130) can further generate a value from at least the token value and display this value as proof of being selected.

摘要： A method for service delivery to a client (110), in which the client (110) selects (216) a service, and establishes (218) a connection with a system server (120) to which it sends (220) an identity (ID) associated with the client (110) and an identifier (CONT_ID) of the service. The system server (120) verifies (222) that the client (110) is authorised to access to the service and (224) that the client (110) is non-emulated. If this is verified, the service is provided to the client (110). In a preferred embodiment, the service is scrambled content (C') and the system server (120) provides (226) a descrambling key (K cont ) to the client (110), and instructs (228) a content server (130) to provide (230) the scrambled content (C') to the client (110). Also claimed are a device, a system, and a system server.

摘要： The invention relates to pairing a slave device with a master device, for example decoders in a conditional access system. There is provided a security module (30, 43, 44) that stores a device state that indicates whether a decoder shall be a master or a slave decoder. There is also provided a method in a conditional access system of providing a device (41, 42) with a device state (CAM_STATE) stored on a security module (30, 43, 44). It is detected that the security module is in connection with the device and the device state is transferred from the security module to the device. There is further provided a method of pairing a slave device (42) with a master device (41). The slave device asks (601) the master device to identify itself, the master device returns (602) an identification, and if the slave device has not yet been paired with a master device, it checks (604) the identity of the master device and, if the identity is verified pairs (607) with the master device. There is also provided a first, slave, device (42) for pairing with a second, master, device (41). The first device comprises an interface (27) for sending an identification command to and receiving an identification message from the master device, and a processor (24) for checking the identity of the second device and pairing the first device with the second device.
摘要翻译：本发明涉及将从设备与主设备配对，例如条件接入系统中的解码器。提供了安全模块（30,43,44），其存储指示解码器应该是主解码器还是从解码器的设备状态。还提供了一种在条件访问系统中提供具有存储在安全模块（30,43,44）上的设备状态（CAM_STATE）的设备（41,42）的方法。检测到安全模块与设备连接并且设备状态从安全模块传输到设备。还提供了一种将从设备（42）与主设备（41）配对的方法。从设备请求（601）主设备标识自身，主设备返回（602）标识，并且如果从设备还没有与主设备配对，则它检查（604）主设备的标识并且如果身份被验证与主设备配对（607）。还提供了用于与第二主设备（41）配对的第一从设备（42）。第一设备包括用于向主设备发送识别命令并从主设备接收识别消息的接口（27），以及用于检查第二设备的身份并将第一设备与第二设备配对的处理器（24）。

摘要： A receiver (300) receives (S24) digital content scrambled using a control word and a user code for the scrambled content. A user inputs the user code that is forwarded to a code extractor (310) that generates (S25) the control word and a user identifier from it. The control word is sent to a descrambler (320), a watermark information generator (330) and a visible watermark insertion unit (350). The descrambler (320) descrambles (S26) the scrambled content using the control word, an invisible watermark insertion unit (340) inserts invisible watermark information obtained from the watermark information generator (330) into the descrambled content and the visible watermark insertion unit (350) inserts the user identifier as a visible watermark. Also provided are a corresponding method for processing digital content and a method and a device for generating the user code.

摘要： A host (110) reads host software code (131) and secure processor software code (132) of an software application (130) and passes the secure processor software code (132) to the secure processor (120) that requests an activation sequence (133) for the software application (130) from a remote server (260). The secure processor (120) receives the activation sequence (133) for the software application (130) and applies it to the secure processor software code (132) to make it executable. The host (110) executes the host software code (131) and calls a procedure of the executable secure processor software code (132) in the secure processor (120), which executes the procedure of the executable secure processor software code (132) to obtain a response to the call that is then returned. The activation sequence (133) is advantageously software code. The invention can enable protection of a plurality of software titles using a single secure processor that is dynamically adapted for each title.
