USING ACROBAT 9 STANDARD 234 Security 8 From the Use Digital ID For menu, choose whether you want to use the digital ID for signatures, data encryption, or both. Click Finish. You can export and send your certificate file to contacts who can use it to validate your signature. Important: Make a backup copy of your digital ID file. If your digital ID file is lost or corrupted, or if you forget your password, you cannot use that profile to add or validate signatures. Set up a roaming ID account A roaming ID is a digital ID that is stored on a server and can be downloaded-at the subscriber's request-to the roaming subscriber's location. You must have a working Internet connection to access a roaming ID and an account from an organization that supplies roaming digital IDs. 1 Do one of the following: • In Acrobat, choose Advanced > Security Settings. • In Reader, choose Document > Security Settings. 2 Expand Digital IDs on the left, select Roaming ID Accounts, and click Add Account. 3 Type the name and URL for the roaming ID server, and click Next. 4 Type the user name and password you've been assigned or follow the directions to create an account. Click Next, and then click Finish. 5 Select your roaming ID to use it, or click Logout. When you perform a task that uses your roaming ID, you're automatically logged in to the roaming ID server if your authentication assertion hasn't expired. Smart cards and hardware tokens A smart card looks like a credit card and stores your digital ID on an embedded microprocessor chip. You can use the digital ID on a smart card to sign and decrypt documents on devices that include a smart card reader. Similarly, a security hardware token is a small, keychain-sized device that you can use to store digital IDs and authentication data. You can access your digital ID by connecting the token to a USB port on your computer or mobile device. Some smart card readers include a keypad for typing a personal identification number (PIN). If you store your digital ID on a smart card or hardware token, specify that information when you sign or certify documents.
