Security Technology

Fifth Third Bank is committed to preserving the integrity of our customer account relationships. Accordingly, our online applications and services utilize advanced Internet security technology.

1. Encryption
   
   Encryption is the process of transforming information into an indiscernible coded message. Information transmitted while accessing account information over the Internet or submitting an online application is encrypted using Secure Sockets Layer (SSL) Technology, a state-of-the-art encryption process developed by Netscape Communications Corporation.
   
   This process utilizes a unique mathematical formula or "Key" to encrypt your information. Encryption strength is measured by the length of the "Key" used to encrypt the data. Longer "keys" provide more effective encryption. Browsers generally offer two levels of encryption strength:
   
   40-Bit Encryption Key (International Grade Encryption) measures 2⁴⁰ possible keys.
   128-Bit Encryption Key (Domestic Grade Encryption) measures 2¹²⁸ possible keys.
2. Digital Certificate
   
   A Digital ID is an electronic fingerprint bonded to the "keys" used to encrypt information transmitted over the Internet. Referred to as a Digital Certificate, this unique identifier substantiates Fifth Third Bank's identity to your browser.
   
   

   Fifth Third Bank is registered with the certificate authority, VeriSign, and has obtained digital certificates for www.53.com and its subdomains. To check the validity of the site's certificate and authenticity, please click the VeriSign seal.

3. Authentication
