If you consider an RFID system to identify and manage your data inventory procedures, you must invest in more than plain software and hardware. After all, you have to protect and process the data efficiently.
The data stored inside an RFID system is of utmost significance. Unfortunately, this means that hackers may also find it valuable besides you and your clients.
The following write-up specifies a couple of ways, implementing which you may prevent the data from falling into the wrong hands. Please check it out right away.
The experts providing the best personnel tracking system said it is better when a tag remains inactive until someone physically presses a switch or button. In other words, nobody can read the tag until its owner provides consent. This trick is especially effective for personal possessions.
- Mutual Authentication
The sensor sends a code to the tag. You can decipher it only with a key. After the tag is activated, it sends the same code to the reader for interpretation. An imposter would not be able to decipher the code and access the data because he/she has no idea about the special key.
Insulated shields encompass the tag and can only be removed by the owner. Although they function seamlessly on a personal level, they can be quite labour-intensive in warehouse premises. This trick does not depend on any form of encryption; hence, it is considered affordable.
- Lock Password
A lock password is a 32-bit password. If you want the tag to transmit data, you must provide the password. Hackers can never guess the password because the 32-bit passwords have over 4294967267 probable combinations. This is a simple yet effective way to safeguard the passive ultra-high frequency solutions with inadequate computational abilities.
- Kill Code
According to the experts offering top-notch RFID asset tracking system, encryption can also be utilized for killing tags. However, this is not always a viable option. Once the tag is killed, it will be rendered unresponsive to legitimate readers and hackers.
- Cover Coding
The reader’s signal is louder than the tag’s. The outsiders can thus pick up its transmissions easily. Cover coding makes use of this disparity to keep hacking at bay. At first, the reader asks for a random number from a tag. The tag provides the number but quietly. The reader encrypts further communications using the number, making it impossible for any third party to gain access.
- One-Sided Encryption
One-sided encryption has acquired extensive popularity. Here only the reader participates in the encryption. The data transmitted to the tag will be encrypted. The data sent back to the reader by the tag could be decrypted only by the reader. Since the computation happens inside the reader, the tag remains cheap and simple. If the hacker gets hold of the tag, he will not understand its data.
Now that you know how to keep the data embedded within an RFID system safe, it is time to find out what methods the uninvited parties undertake to access your data illicitly.
Skimming involves secretly reading the tag, generally via a handheld reader. If your RFID system is configured in adherence to a well-known protocol, it may get skimmed. Eavesdropping is also quite popular. Even though you cannot see or hear it, the conversation between a tag and a reader happens in physical space. Someone may pick on this conversation using a receiver. They may steal the data during the legitimate exchange.
