摘要： A method for data embedding in a digital image under the constraint of a pre-specified upper bound value on the amount of change in the value of a property associated with the image. For compression tolerant data hiding in digital images, a property is selected in which the required information can be embedded. The property should be such that the value obtained from the property before and after a lossy compression does not change by a significant amount, and the change should be bounded. The property should be such that a property value as obtained from the image will not vary due to compression, but only due to malicious tampering. The value obtained from the property is stored so that the image can be verified. The complete image is considered in deciding whether to increase or decrease the property value in a particular region. The method also takes into account the fact that blocks having values of 0 or L, corresponding to the minimum and maximum property values, respectively, are incapable of change in a particular region. The method also attempts to vary even the checksum (stored information), in addition to modifying the image so that the net resultant checksum and the modified image coincide with each other.
摘要翻译：一种用于在预先指定的上限值的约束下数字嵌入数字图像的方法，该方法是与图像相关联的属性的值的变化量。对于隐藏在数字图像中的压缩容忍数据，选择可以嵌入所需信息的属性。财产应该是从有损压缩之前和之后的财产获得的价值不会有大量的变化，变化应该是有限的。属性应该使得从图像获得的属性值不会因压缩而变化，而只是由于恶意篡改。存储从属性获得的值，以便可以验证图像。在决定是否增加或减少特定区域中的属性值时考虑完整的图像。该方法还考虑到具有对应于最小和最大属性值的值为0或L的块在特定区域中不能改变的事实。除了修改图像之外，该方法还尝试改变校验和（存储的信息），使得净结果校验和和修改的图像彼此一致。

摘要： A verification system for still images that embeds a watermark so that no visual artifacts are created in the images and thus maintains the visual quality of the image. The algorithm embeds information in an uncompressed image so as to later detect the alteration of the image, as well as the location of the alteration. The embedding of information into a source image is based on a defined mapping process. An image plane consists of macroblocks, which are themselves comprised of microblocks. A code is embedded corresponding to the value of this image property in each macroblock. The specific sequence of microblocks used for embedding this information in the watermarking image plane is a unique function of this property for the corresponding set of microblocks in the indexing image plane. This information can be later decoded from the stamped image. The watermark is embedded by combining the pixel values of the image with the watermark. The watermark is altered if the image is altered.

摘要： A multimedia client receives, over a subscription multimedia network, television content for presentation to a viewer, where the television content includes an advertising break and identifies a keyword associated with the television content. The multimedia client sends, over the subscription multimedia network, the keyword to an advertisement server and receives from the advertisement server, an advertisement corresponding to the keyword. The multimedia client then provides, for display to the viewer, the advertisement within the advertising break.

An exemplary method may include receiving, from a set top box, information indicative of criteria associated with targeted advertisement; and determining, at a set top box, whether the criteria corresponds to a characteristic of a household at which the criteria is received. The method may also include joining, from a set top box, a multicast group associated with the criteria in the event the criteria is determined to correspond to the characteristic of the household at which the criteria is received. The method may also include receiving, via multicast, at a set top box, the targeted advertisement associated with the criteria; and displaying, at a video display device, the targeted advertisement. The exemplary method may allow efficient and unconstrained information distribution leading to improved application quality and performance.
