摘要： Methods, devices and computer program products facilitate conditional access to a content embedded with watermarks. For such a content, when copy control rules associated with an embedded watermark message prohibits unconditional access to the content, it is determined whether or not an exception to the copy control rules exists, and if an exception to the copy control rules exists, the content is conditionally accessed. Additional watermark messages can be extracted while the content is being conditionally accessed, and based on the additionally extracted watermark messages, it is verified that conditional access to the content has been fulfilled.

摘要： A technique for determining authenticity of analog forms such as packaging or documents determines whether the analog form has been made directly from a digital representation or by photocopying or scanning an analog form. The technique makes the determination by comparing an original digital representation of a portion of the analog form having an authentication pattern with a digital recording of the portion from the analog form and measuring differences in features that are affected by the operations of photocopying or scanning. The authentication pattern may depend on a key or on other information displayed on the analog form. Another pattern may be displayed on the analog form to locate the pattern.

摘要： A container tank body and a processing method thereof are provided. The tank body is arranged in a frame with a square-shaped cross section and comprises a cylindrical main body part, end enclosures arranged at two ends of the cylindrical main body part and fixedly connected with the cylindrical main body part, and a tank body strengthening device. The cylindrical main body part comprises a plurality of parts with an arc-shaped cross section, the parts are formed by bending and welding a same panel, and the cross section of the cylindrical main body part of the tank body is generally arranged between the square-shaped cross section of the frame and an inscribed circle of the square-shaped cross section. A tank container comprising the tank body is also disclosed. As the cylindrical main body part is made by continuously bending a whole panel, the molding process is simplified so that the cylindrical main body part is only provided with one welding line, thereby remarkably lowering the leakage risk of the container tank body in use and improving the reliability of the container tank body in work; and the structure has quite strong self-anti-load capacity, thereby decreasing the number of the used tank strengthening devices and reducing the deadweight.

摘要： An apparatus for providing a combined digital signal comprises a bit adder and a combiner. The combined digital signal contains information of a first digital input signal and a second digital input signal, wherein a block length of the first digital input signal is shorter than a block length of the second digital input signal. The bit adder is configured to add at least one filling bit to a block of the first digital input signal to obtain an adapted first digital input signal, so that the block length of the adapted first digital input signal is equal to a block length of the second digital input signal. The combiner is configured to combine the adapted first digital input signal and the second digital input signal to obtain and provide the combined digital signal.

摘要： Techniques for determining authenticity of analog forms such as packaging or documents (117). One of the techniques determines whether the analog form has been made directly from a digital representation (903) or by photocopying or scanning an analog form. The technique makes the determination by comparing (911) an original digital representation of a portion of the analog form with a digital recording (203) of the portion from the analog form and measuring differences in features that are affected by the operations of photocopying or scanning. The original digital representation (105) and the analog form may have a “noisy”, i.e., random or pseudo random pattern. Such noisy patterns may further be used for other authentication purposes, such as determining whether the portion of the analog form that has the noisy pattern has been altered and to carry hidden messages. The noisy pattern may carry a logo or may be. part or all of a barcode.
