DNS name resolution is integrated into each node in a network storage cluster, to allow load balancing of network addresses, using a weighted random distribution to resolve DNS requests. A node in the cluster gathers statistics on utilization of resources, such as CPU utilization and throughput, on nodes in the cluster and distributes those statistics to all other nodes. Each node uses the same algorithm to generate weights for the various IP addresses of the cluster, based on the statistics distributed to it. The weights are used to generate a weighted list of available network addresses. In response to a DNS request, a DNS in a given node randomly indexes into the weighted address list to resolve requests to a network address. The weights are chosen so that the DNS is likely to pick an IP address which has a low load, to balance port and node usage over time.

A computer-implemented method and apparatus for embedding hidden data in an audio signal. An audio signal is received in a base domain and then transformed into a non-base domain, such as cepstrum domain or LP residue domain. The statistical mean manipulation is employed on selected transform coefficients to embed hidden data. The introduced distortion is controlled by psychoacoustic model to ensure the imperceptibility of the embedded hidden data. Scrambling techniques can be plugged in to further increase the security of the data hiding system. The present new audio data hiding scheme provides transparent audio quality, sufficient embedding capacity, and high survivability over a wide range of common signal processing attacks.

An image in a base domain (e.g., spatial) is restored from only one component (e.g., magnitude) of a transform-domain (e.g., Fourier) image by combining this component with a complementary component (e.g., phase) of a transformed previous iteration. Every iteration is converted to the base domain, and predefined known marker and padding data is reapplied to the iteration during every iteration, for convergence purposes. The restored image can be scaled and trimmed, and the marker position interpolated. The original image to be restored is modified to contain the known marker and known padding at known locations. These may be inserted in the base domain or in the transform domain.
