Disclosed are methods, systems, and non-transitory computer-readable medium for detecting data anomalies on a device. The method may include determining data patterns for data input to the device, data output from the device, and/or data stored in a memory of the device; monitoring the data input, data output, and the data stored in the memory at least based on the determined data patterns in parallel with processing of the data input, data output, and/or the data stored in the memory; and detecting whether an anomaly exists in the data input, data output, and/or the data stored in the memory of the device based on the monitoring.
