An electronic notary shall use a tamper-evident technology that complies with Section 2410 to produce the notary's electronic signature in a manner that is capable of independent verification.
An electronic notary shall take reasonable steps to ensure that no other individual may possess or access the notary's electronic signature.
An electronic notary shall keep in the sole control of the notary all or any part of a tamper-evident technology whose exclusive purpose is to perform electronic notarial acts.
