Smart cards can’t be read in the same way that traditional credit and debit cards can since they don’t have magnetic strips. They’re read using either physical slots designed for reading chips or short-range Wi-Fi via near-field communication. Smart cards may be used for a number of identifying reasons in addition to sending financial information.
Smart Card
A smart card is a plastic card with an integrated chip that functions as a security token. These cards can be made of metal or plastic and are usually the same size as a driver’s license or credit card. By direct physical contact (also known as chip and dip), or a short-range wireless connectivity standard like radio-frequency identification (RFID) or near-field communication, they can communicate with the reader.
A microcontroller or an integrated memory chip can be found on a smart card. Smart cards are supposed to be tamper-resistant and employ encryption to safeguard information stored in memory. Microcontroller-equipped cards can do on-card processing and alter data stored in the chip’s memory.
Features of Smart Card
Smart cards—cards having incorporated integrated circuits that can process data—provide privacy protection in an access control system with a variety of characteristics. Take a look at these:
- Authentication- Others who want access to the card can use smart cards to authenticate themselves. These procedures can be used to verify people, devices, or programs that want to use the card’s chip data. These features, for example, can safeguard privacy by verifying that a banking application has been validated as having the required access privileges before accessing financial data or card functionalities.
- Secure Data Storage- Smart cards allow you to store data securely on the card. Only individuals with valid access credentials can access this data via the smart-card operating system. A system might leverage this feature to improve privacy by keeping the data of users on the card rather than in a central database. In this circumstance, the user has a greater understanding and control over when and to whom their personal data is given access.
- Encryption- Smart cards provide a comprehensive range of encryption features, including key creation, safe key storage, hashing, and digital signatures. In a variety of ways, these skills can be employed to safeguard privacy. A smart-card system, for example, can generate a digital signature for an e-mail message, allowing the validity of the message to be verified. This safeguards the communication against tampering and gives the receiver confidence in the message’s authenticity. The fact that the signature key came from a smart card lends credence to the signer’s origin and intent.
- Personal Device- Of course, a smart card is a personal and portable gadget connected with a certain cardholder. The smart-card plastic is frequently customized, resulting in a tighter bond between the cardholder and the card. While these traits are self-evident, they may be used to increase privacy. To increase the accuracy and privacy of patient prescriptions, a healthcare application can choose to save prescription information on the card rather than on paper.
- Secure Communications- Smart cards allow the card and reader to communicate in a secure manner. Data can be sent and received from smart cards in a secure, private way, similar to security standards used in many networks.
- Device Security- Smart-card technology is tamper-resistant and incredibly difficult to replicate or falsify. Smart-card chips have a number of hardware and software features that identify and react to tampering attempts, as well as assist in the prevention of assaults.
- Biometrics- Smart cards can be used to contain biometric templates and conduct biometric matching operations in a safe manner. These properties can be utilized to increase the privacy of biometric systems. For example, in a single-sign-on system that employs fingerprint biometrics as the single sign-on credential, keeping fingerprint templates on smart cards rather than in a central database could be an effective technique to improve privacy.
- Certifications- Many smart cards and gadgets on the market today have been approved to meet industrial and government security requirements. They can only get these credentials after passing stringent testing and evaluation requirements administered by independent certifying organizations. These certifications aid in the protection of privacy by ensuring that the smart card hardware and software’s security and privacy features and functions work as intended.
Smart cards allow the bearer and third parties that want access to the card to be identified and authenticated in a secure manner. For example, a cardholder can authenticate using a PIN code or biometric data. They also allow for the safe storage of data on the card and the encryption of conversations.
Why are smart cards a better option than other types of ID tokens?
Smart cards are commonly regarded as among the most secure and dependable electronic identity (ID) tokens available. An embedded integrated circuit chip in a smart card can be a microcontroller chip with internal memory or a secured memory chip on its own. The card connects with a reader by direct physical touch or a contactless electromagnetic field that energizes the chip and transmits data between the card and the reader. Smart cards have the unique ability to store large amounts of data, perform on-card functions (e.g., data storage and management, encryption, decryption, and digital signature calculations), and interact intelligently with a smart card reader thanks to an embedded microcontroller.
A smart card ID can include an integrated chip, visible security marks, magnetic stripe, barcode, and/or optical stripe, among other ID technologies. The resultant ID may enable both future and legacy physical and logical access applications by merging these multiple technologies into a smart card ID token. Other applications that usually need separate ID processes and tokens can also benefit from them.
Many contemporary identity management systems incorporate biometrics to increase the accuracy of identifying people. What role may smart cards play in ensuring privacy in a biometrics-based system?
Smart cards are a highly effective way to preserve an individual’s privacy when they are required to utilize a biometric identity system.
- Instead of being maintained in an online database, biometric information can be saved on a smart card, giving the biometric owner control over the physical ownership of the card containing the individual’s biometric data.
- At the card/reader level, biometric data may be protected using cutting-edge encryption techniques while still enabling full three-factor authentication.
- You have something – the card with all of its security features.
- Something you’re familiar with, such as a password or a PIN (PIN)
- The biometric is something you are.
- Instead of delivering the stored biometric information to the reader for matching in a smart card-based application, the individual’s biometrics can be acquired by a reader and provided to the smart card for matching. The biometric information of the person would never leave the card, effectively eliminating any risk of compromise.
In a smart card-based application, instead of giving the recorded biometric data to the reader for matching, the individual’s biometrics can be obtained by a reader and supplied to the smart card for matching. The person’s biometric data would never leave the card, thereby removing any chance of compromise.
Conclusion
It’s vital to remember that the business supplying the contactless device, card, or document must incorporate data privacy and security into the application at the system level. Issuing businesses must have policies in place to fulfill the application’s security and privacy needs, and then install the right technology to offer those features. The capacity of contactless smart card technology to enable a wide range of security features gives businesses the freedom to apply the amount of security that is appropriate for the application’s risk.
