    摘要： The overlay human interactive proof system (“OHIPS”) and techniques described herein operate in conjunction with any known or later developed computer-based applications or services to provide secure access to resources by reliably differentiating between human and non-human users. Humans have a generally superior ability to differentiate misaligned characters or objects from correctly aligned ones. As such, the OHIP splits an image including one or more visual objects into two or more partial images to form a HIP. The partial images may also be further split into groups of sub-partial images, and/or the partial images (or the sub-partial images) may be moved, so that at any given alignment position, a user can recognize only some visual objects. A user is instructed to reassemble the partial images at one or more predetermined alignment positions using a GUI, and the user is asked to identify information regarding one or more visible objects.

    摘要： Systems and methods configured for recoding an odd integer and elliptic curve point multiplication are disclosed, having general utility and also specific application to elliptic curve point multiplication and cryptosystems. In one implementation, the recoding is performed by converting an odd integer k into a binary representation. The binary representation could be, for example, coefficients for powers of two representing the odd integer. The binary representation is then configured as comb bit-columns, wherein every bit-column is a signed odd integer. Another implementation applies this recoding method and discloses a variation of comb methods that computes elliptic curve point multiplication more efficiently and with less saved points than known comb methods. The disclosed point multiplication methods are then modified to be Simple Power Analysis (SPA)-resistant.

    摘要： A digital watermarking method performs tonal detection on a signal (e.g., audio) to identify tonal and non-tonal components. These components are analyzed to compute appropriate weighting of a digital watermark for the tonal and non-tonal components. This tonal detection method is also used in recovering the watermark. A decoding method performs tonal detection on a watermarked signal, computes weights for tonal and non-tonal components, and recovers the embedded watermark using the weights. The same or different watermark embedding schemes may be used to embed digital watermarks in the tonal and non-tonal components. Tonal analysis is used in conjunction with frequency and temporal shaping to adapt the digital watermark to the signal in which it is embedded.
