JPMorgan Chase's COIN platform is one example of this approach in action. It uses machine learning to review and interpret commercial loan agreements. It's reportedly responsible for reducing document review time from 360,000 hours to seconds. This efficiency not only brings down operational costs but also enhances decision-making and customer experiences.
Biometric security has become a cornerstone in the finance industry, offering a robust mechanism for secure customer identification. Financial institutions now routinely deploy fingerprint scanning, facial recognition, and voice identification to provide secure and convenient user access.
Use cases span from mobile and online banking apps using fingerprints and facial recognition to ATMs with voice verification. These systems rely on Al models, like CNNs, for image recognition and recurrent neural networks (RNNs) for voice pattern analysis. In turn, these models are typically developed using frameworks like TensorFlow and Keras.
An illustrative case study is HSBC's use of voice recognition to verify customer identities. Voice ID drastically reduces the time spent on customer authentication, often a frustrating part of the telephone support experience. Similarly, Wells Fargo and many other banks use multiple modalities for biometric authentication on their mobile apps.
