Digital IDs FAQA digital ID is like an electronic driver’s license or passport that proves your identity. A digital ID usually contains your name and email address, the name of the organization that issued it, a serial number, and an expiration date. Digital IDs are used for certificate security and digital signatures. Digital IDs contain two keys: the public key locks, or encrypts data; the private key unlocks, or decrypts that data. When you sign PDFs, you use the private key to apply your digital signature. The public key is in a certificate that you distribute to others. For example, you can send the certificate to those who want to validate your signature or identity. Store your digital ID in a safe place, because it contains your private key that others can use to decrypt your information.  You don’t need a digital ID for most of the work you do in PDFs. For example, you don’t need a digital ID to create PDFs, comment on them, and edit them. You need a digital ID to sign a document or encrypt PDFs through a certificate. Self-signed digital IDs can be adequate for personal use or small-to-medium businesses. Their use should be limited to parties that have established mutual trust. Most business transactions require a digital ID from a trusted third-party provider, called a certificate authority. Because the certificate authority is responsible for verifying your identity to others, choose one that is trusted by major companies doing business on the Internet. The Adobe website gives the names of Adobe security partners that offer digital IDs and other security solutions. See Adobe Approved Trust List members. Unfortunately, you cannot recover or reset the password if you’ve forgotten it. If you created the ID yourself, you can create a new one with the same information that you used for the ID. If you got the ID from a certificate authority, contact the authority for help. Create a self-signed digital IDSensitive transactions between businesses generally require an ID from a certificate authority rather than a self-signed one.
Register a digital IDTo use your digital ID, register your ID with Acrobat or Reader.
Specify the default digital IDTo avoid being prompted to select a digital ID each time your sign or certify a PDF, you can select a default digital ID.
Change the password and timeout for a digital IDPasswords and timeouts can be set for PKCS #12 IDs. If the PKCS #12 ID contains multiple IDs, configure the password and timeout at the file level. Self-signed digital IDs expire in five years. After the expiration date, you can use the ID to open, but not sign or encrypt, a document.
Be sure to back up your password in a secure place. If you lose your password, either create a new self-signed digital ID and delete the old one, or purchase one from a third-party provider. Delete your digital IDWhen you delete a digital ID in Acrobat, you delete the actual PKCS #12 file that contains both the private key and the certificate. Before you delete your digital ID, ensure that it isn’t in use by other programs or required by any documents for decrypting. You can delete only self-signed digital IDs that you created in Acrobat. A digital ID obtained from another provider cannot be deleted.
Protecting digital IDsBy protecting your digital IDs, you can prevent unauthorized use of your private keys for signing or decrypting confidential documents. Ensure that you have a procedure in place in the event your digital ID is lost or stolen. How to protect your digital IDsWhen private keys are stored on hardware tokens, smart cards, and other hardware devices that are password- or PIN-protected, use a strong password or PIN. Never divulge your password to others. If you must write down your password, store it in a secure location. Contact your system administrator for guidelines on choosing a strong password. Keep your password strong by following these rules:
To protect private keys stored in P12/PFX files, use a strong password and set your password timeout options appropriately. If using a P12 file to store private keys that you use for signing, use the default setting for password timeout option. This setting ensures that your password is always required. If using your P12 file to store private keys that are used to decrypt documents, make a backup copy of your private key or P12 file. You can use the backed up private key of P12 file to open encrypted documents if you lose your keys. The mechanisms used to protect private keys stored in the Windows certificate store vary depending on the company that has provided the storage. Contact the provider to determine how to back up and protect these keys from unauthorized access. In general, use the strongest authentication mechanism available and create a strong password or PIN when possible. What to do if a digital ID is lost or stolenIf your digital ID was issued by a certificate authority, immediately notify the certificate authority and request the revocation of your certificate. In addition, you should not use your private key. If your digital ID was self-issued, destroy the private key and notify anyone to whom you sent the corresponding public key (certificate). Smart cards and hardware tokensA smart card looks like a credit card and stores your digital ID on an embedded microprocessor chip. Use the digital ID on a smart card to sign and decrypt documents on computers that can be connected to a smart card reader. Some smart card readers include a keypad for typing a personal identification number (PIN). 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. If you store your digital ID on a smart card or hardware token, connect it to your device to use it for signing documents. What is a method used to verify the identity of computer users?In authentication, the user or computer has to prove its identity to the server or client. Usually, authentication by a server entails the use of a user name and password. Other ways to authenticate can be through cards, retina scans, voice recognition, and fingerprints.
Which of the following uses information from the human body to verify identity?Definition(s): A measurable physical characteristic or personal behavioral trait used to recognize the identity, or verify the claimed identity, of an applicant. Facial images, fingerprints, and iris scan samples are all examples of biometrics.
When someone logs into a website such as Google and it requires them to enter both password and a code sent to their smartphone this is referred to as what?Two-factor authentication (2FA) is a security system that requires two separate, distinct forms of identification in order to access something. The first factor is a password and the second commonly includes a text with a code sent to your smartphone, or biometrics using your fingerprint, face, or retina.
What is a high level of encryption for wireless devices?AES — The Advanced Encryption Standard (AES) encryption algorithm a widely supported encryption type for all wireless networks that contain any confidential data. AES in Wi-Fi leverages 802.1X or PSKs to generate per station keys for all devices. AES provides a high level of security like IP Security (IPsec) clients.
