A method and system of authenticating a computer resource such as an application or data on a mobile device uses a contactless token to provide multi-factor user authentication. User credentials are stored on the token in the form of private keys, and encrypted data and passwords are stored on the device. When an application user requires access to the resource an encrypted password is transmitted to and decrypted on the token using a stored key. An unencrypted data encryption key or password is then transmitted back to the device under the protection of a cryptographic session key which is generated as a result of strong mutual authentication between the device and the token.

A method for retrofitting DNA in a single-copy or high-copy vector, such as a fosmid or BAC, whereby an artificial transposon is used to introduce a conditional multi-copy origin of replication (“ori”) into the DNA in said vector. Following random in vitro or in vivo transposition of the ori-containing transposon into DNA in the single-copy or low-copy vector, the resulting insertion clones are introduced into a special host strain that contains a gene which encodes a polypeptide required for replication from the multi-copy ori. However, since the gene for this polypeptide is expressed from a tightly-regulated inducible promoter, the polypeptide is not expressed in the absence of inducer. On addition of inducer to the culture medium, the host cell synthesizes the polypeptide, which in turn activates replication from the multi-copy ori, thereby increasing the amount of clone DNA synthesized by the cell.

A method and system of conducting a cryptocurrency payment via a mobile device, using a contactless token to store and protect a user's secret key. A cryptocurrency wallet encrypted with the secret key is received by the mobile device from the token. A cryptocurrency payment instruction is received by the mobile device, prompting for a user credential to approve the instruction. In response the mobile device sends to the token a message comprising the encrypted wallet together with the payment instruction and the user credential. Using the secret key, the token then decrypts the cryptocurrency wallet from the encrypted wallet and creates a payment transaction by digitally signing the payment instruction, and transmitting the payment transaction to a cryptocurrency network or exchange. Confirmation of the transaction requires either a PIN, biometric or fingerprint on the mobile device, or authentication via button press, PIN or fingerprint on the token.
