Abstract: In one embodiment, a watermark is embedded in a sequence of video frames, for each one of the video frames, a set of N rectangular patches, two palettes of pixel values in a selected color space, such that the two palettes are denoted as P0 and P1, and P0?P1, and in each one of the N patches a processor which chooses one of P0 and P1 according to a value of a payload bit to be encoded, a calculator which calculates one of a variance of pixel values in the frame, and edginess for the pixel values in the frame, thereby determining a calculated value, and a processor which determines if the calculated value is beneath a given threshold value, if the calculated value is beneath the given threshold value the processor is operative to calculate a function of the pixel values, the closest value to a result of the calculation of the function in the chosen palette is chosen, and a replacer which replaces the pixel values within the patch with the chosen closest value.

Abstract: A Headend system including a encoder to encode input data yielding a plurality of data packets, each of the packets having a header and a payload, a post encoding processor to identify ones of the data packets having a payload with a suspected known plaintext, and modify at least some of the identified packets, and an encryption processor to encrypt at least some of the data packets yielding encrypted data packets. Related apparatus and methods are also described.

Abstract: In one embodiment, a system including a processor is operative to receive a content item including a watermark encoding a series of encrypted bits deriving from encrypting an information element multiple times, extract at least some encrypted bits from at least part of the watermark, decrypt a series of N bits using a first key yielding a first value, the series of N bits including Q bits of the encrypted bits and K, greater than, or equal to zero, guessed bits, re-encrypt the first value using a second key yielding a second value, and compare at least part of the second value to M bits of the encrypted bits to determine if at least part of the second value matches the M bits in order to provide a level of confidence that the first value is the information element which was encrypted and embedded as the watermark.

Abstract: In one embodiment, a system including a processor is operative to receive a content item including a watermark encoding a series of data values of an output stream of a linear feedback shift register initialized with a seed including an information element and an assurance value, the shift register having a plurality of states each including a first and second value, identify at least part of the watermark in the content item, extract at least some of the data values from the at least part of the identified watermark, process at least some of the extracted data values yielding the initial state of shift register, and authenticate the first value of the initial state using the second value of the initial state in order to confirm that the first value is indeed the information element included in the seed processed by the shift register.

Abstract: The present invention relates to compositions and methods for enhancing the growth of infants. Particularly, the present invention discloses the use of insulin for promoting the growth of low birth weight infants, including preterm infants and small for gestational age (SGA) infants over the expected rate.

Abstract: An infusion tracker comprising a base and a cover configured to be assembled onto the base. The infusion tracker further comprises a memory tag, attached to one of the base and the cover and configured to store data and operable to wirelessly release stored data in a format readable by a processor-controlled device or to activate an application software. The infusion tracker is further configured to enclose a portion of an infusion line between two ends of the portion, the portion being enclosed substantially between the base and the cover.
