Fingerprint authentication using QCA technology

Quantum dot Cellular Automata based Fault Tolerant Fingerprint Authentication Systems using Reversible Logic Gates

“…Here QCA cost is the product of total area and square of latency. In addition to this, parameter by parameter wise percentage improvement compared to existing design [36] is presented in Table 4. It is seen that the proposed FAS designs show an improvement ranging from 13.51% to 59.46% in terms of number of cells, 29.94% to 67.16% improvement in cell area, 11.12% to 67.14% improvement in total area, 33.33% to 66.67% improvement in latency and 60.51% to 90.51% improvement in terms of QCA circuit cost.…”

“…This operation can be visualized using the operating mechanism depicted in Figure 7. One such fingerprint authenticator (FPA) has been presented in [36], using a 2×2 Feynman Gate (shown in Figure 8).…”

“…Debnath et al in [36] presented an FPA by modifying the input A (written as X) to A' (written as X') of the Feynman gate as depicted in Figure 9.…”

“…FPA proposed in [36] The QCA implementation of this FPA, shown in Figure 10, by Debnath et al in [36] was done using the equations based on the majority voter concept = ̅…”
