在选择标准之后，生物识别技术有两个步骤：验证和识别。在验证步骤中，首先，为所有个体创建参考数据，其次，将该参考数据与随机选择的样本进行匹配。在鉴别步骤中，将目标样品与参比品进行匹配以进行鉴别，这有助于确认鉴别（阳性鉴别）或拒绝鉴别（阴性鉴别）。在他或她与生物识别机器的第一次交互中，该人将他登记到系统中，使得在个人与系统的任何进一步交互中完成匹配。在大多数设置中，这种生物识别是通过使用单一标准来完成的，并且面临着经常失败的批评，例如。如果使用视网膜尺度，并且人患有一些眼睛问题，在指纹的情况下，如果手指截肢发生等。因此，最新的概念是具有多模态生物识别系统，如指纹，视网膜指纹等的组合。这，不仅可以避免由于单点数据的黑客攻击而产生的问题，而且在一个参数不能用于一个或多个参数的情况下也很有用。另一个原因
After selection of criteria, there are two steps in biometrics; verification and identification. In verification step, firstly, reference data is created for all individuals, secondly, this reference data is matched with randomly selected samples. In identification step the target sample will be matched against the reference for identification, this can help to confirm the identity (positive identification) or reject the identity (negative identification). In his or her first interaction with the biometric machine the person enrolls him for the system so that the matching be done in any further interaction of individual with the system. In majority of setups this biometric identification is done by using a single criteria and faces criticism for frequent failures, eg. If retinal scale is used and person is suffering from some eye problem, in case of fingerprints if finger amputation happens and so on. Thus, the latest concept is to have a multimodal biometric system like a combination of fingerprint, retinal prints and so on. This, will not only avoid problems arising due to hacking of single point data but can also be useful in situations where one parameter cannot be used for one or the other reason.
