Note that the catchlog.com proposed design does not capture and transmit an image of a fingerprint, and would not, for example, allow matching of a skippers fingerprint against police fingerprint records. Instead, they have designed an algorithm that turns the input from the fingerprint reader into a verification number that is characteristic for a particular individual and consistent over time. The verification number is only reproducible with specific fingerprint reader technology and algorithms. Therefore there is a required eSignature registration process whereby a skipper is associated with a particular fingerprint verification number; then, whenever eLogbook data is "signed", the skipper must pass his fingers over the fingerprint reader, at which point the catchlog.com software will bind the verification number to the data.

eSignature (myAlaska)

myAlaska is an authentication and electronic signature system allowing citizens to interact and execute electronic signatures with multiple State of Alaska services through a single user name and password. Participation in myAlaska is voluntary and limited to individuals who meet prerequisites which vary based on the type of transaction. (For example, some transactions are only available to participants who verify their identity with a valid Alaska driver license.)

A myAlaska electronic signature uses cryptography-based mechanisms to bind the data to be signed with the identity of the signer (myAlaska identity) and the date and time of the signing act. Due to this cryptographic binding, at any time after the signing act an independent third party can confirm non-repudiation (a person with knowledge of a particular myAlaska user name and password signed it, and no one else could have) and integrity (a change to any element of the content will be detectable via the cryptographic mechanism; i.e., the signature makes the content tamper-evident). The myAlaska system implements an electronic signature by packaging the data to be signed, the myAlaska identity of the signer, the date and time of the signing act, and the identity of the agency requesting the signature into one XML document and then digitally signing that XML document with an X.509 certificate issued to the myAlaska system.

myAlaska is currently in use for a dozen citizen-to-government and business-to-government services and has a volume of approximately 200,000 transactions per year.
