A method for providing secure transactions generates a Secure Card Number (“SCN”) for a first entity that is transferred with a first entity identifier to a second entity and then to a money source that verifies that the transaction is valid by use of the first entity identifier and the SCN. The SCN includes a Transaction Information Block (“TIB”), a Counter Block, and an encrypted Personal Identification Number (“PIN”) Block. The SCN is transferred to the money source in an account number or a non-account data field. The money source can use the TIB to determine whether the SCN should be used once or multiple times or to identify one of several physical devices, all of which are issued to the first entity, used to generate the SCN. The money source validates the SCN by duplicating the encryption process used to create an encrypted PIN Block and comparing the result to the encrypted PIN Block received with the transaction. A Triple Data Encryption Standard algorithm encrypts a PIN Block generated from a PIN, a Sequence Insertion Number (“SIN”) and a known starting value. The SIN can be a combination of three seed values and a random value generated by a Pseudo Random Number Generator (“PRNG”) initialized with the seed values. A Counter value is associated with the Counter Block and the seed values.

The present invention provides a 2 μm-family plasmid comprising a polynucleotide sequence insertion, deletion and / or substitution between the first base after the last functional codon of at least one of either a REP2 gene or an FLP gene and the last base before the FRT site in an inverted repeat adjacent to said gene.

The construction of a chimeric Pestivirus by the identification of selected regions in the 3′NTR of the viral RNA genome is described where additional RNA sequences can be stably inserted. These sequence insertions in the viral RNA genome were stable in replication and capable of forming infectious, RNase resistant virus particles. This chimeric Pestivirus with a 3′NTR insertion can be utilized as a quality control material in analytical assays for RNA targets, including external, internal controls, quantitative standards in PCR and NAT nucleic acid assays.

A method and system for providing encryption resistant watermarking of data is described. The method and system comprises encoding a string of symbols, each having a respective symbol value, as a sequence of vectors where each vector includes a respective number of repetitions of a sub-vector of a predefined length, such that the respective number of the repetitions in each vector in the sequence is indicative of the respective symbol value of a corresponding symbol in the string. This sequence of vectors is then inserted into the item of content including digital data to apply a watermark to the item of content. This insertion process may involve interleaving the vectors with gaps of known lengths containing arbitrary data and may involve insertion prior to the vector sequence a marker comprising a concatenation of a number of copies of a marker vector. The length of the sub-vector may be chosen to be an integer divisor of a block size of a block cipher that is to be applied to the item of content after application of the watermark thereto.

The present invention discloses a method for determining the sequence, the insertion position and the boundary sequence of an exogenous DNA fragment in a transgenic organism. The method comprises: sequencing the whole genome of a transgenic organism, comparing a sequence A to the whole genome sequence of the transgenic organism, and determining the sequence, the insertion position and the boundarysequence of the exogenous DNA fragment in the transgenic organism, wherein an acceptor organism is treated by a vector containing the exogenous DNA fragment to obtain the transgenic organism, and thesequence A is the following a1), a2) or a3): a1) the full-length sequence of the vector, a2) the sequence of any one DNA fragment derived from the vector and containing the exogenous DNA fragment, and a3) the sequence of the exogenous DNA fragment or any one fragment thereof.
