Alaska Stat. § 45.14.201 – Security procedure

(a) In this chapter, “security procedure” means a procedure established by agreement of a customer and a receiving bank for the purpose of
1. (1) verifying that a payment order or communication amending or canceling a payment order is that of the customer; or
2. (2) detecting error in the transmission or the content of the payment order or communication.
(b) A security procedure may require the use of algorithms or other codes, identifying words or numbers, encryption, call-back procedures, or similar security devices. Comparison of a signature on a payment order or communication with an authorized specimen signature of the customer is not by itself a security procedure.
