摘要： An apparatus for embedding data in information material, the data being a plurality of data items each having a different relative importance. The apparatus comprises an encoding processor operable to encode each of said data items, and a combining processor operable to combine said encoded data items with said information material. The information material provides a limited data embedding capacity, as a result for example of the limited bandwidth of the information material itself. Each of the data items are encoded and embedded to the effect that a proportion of the limited data embedding capacity is allocated to the encoded data items in accordance with the relative importance of these data items. As such, for example, an amount of error protection given to each of the data items can be arranged in accordance with the importance of the data items, whilst still satisfying the limited data embedding capacity. Accordingly, a greater amount of protection can be provided to the more important data items, thereby making these items more robust with respect to any processing of the information material and more likely to be recovered correctly.

摘要： An image processing apparatus is operable to embed data into an image. Images such as those generated from an inter-laced scan may comprise a frame of image data, the frame comprising first and second image fields. The image processing apparatus comprises a combining processor operable to introduce the data to be embedded into at least one of the first and second fields of the image frame. As such a likelihood of a perceivable effect of the embedded data on the image may be reduced, because the images are viewed as a frame. The embedded data may also have an increased likelihood of being detected because some processing may effect the image frame more then the fields of the image. The combining processor may be operable to represent the data to be embedded in a transform domain form, and, in combination with a transform processor, combine the data to be embedded with the first and/or second fields with the image in a transform domain form or a spatial domain form. The transform domain may provide a plurality of sub-bands and the data to be embedded may be introduced into at least one of the sub-bands of the transform domain form of the first and/or second fields of the image. Furthermore, the combining processor may be operable to introduce data to be embedded into at least one other sub-band, and the combining processor may be operable in combination with the transform processor to combine the data in the other sub-band with the frame of image data in the transform or the spatial domain.

摘要： A method of controlling copying of an information signal, comprises the steps of: prior to recordal and/or transmission, applying to the information signal a substantially imperceptible modification representing copy control data including a password securely encoded according to a predetermined algorithm; upon reproduction for copying by a user, deriving (S1, S3) the copy control data from the modified information signal; comparing (S8, S9, S11, S13, S15) the derived securely encoded password with a reference password securely encoded according to a predetermined algorithm; and enabling (S5) copying of the information signal if the securely encoded password derived from the information signal and the securely encoded reference password have a predetermined relationship, otherwise disabling copying (S7). The reference password is sent to the user via a channel which is separate from a channel used to send the information signal to the user.
