Protecto Offers Cutting-Edge Personal Data Identification

Protecto Offers Cutting-Edge Personal Data Identification

In today's world, where datasets are enormous, protecting sensitive personal information has become paramount. Enter Protecto: a tool that brings together a series of powerful models to identify personal data within vast datasets.

Synergizing Diverse Models for Peak Performance

Rather than relying on a single model, Protecto integrates the capabilities of Named Entity Recognition (NER) models, regular expression (regex) patterns, specialized algorithms, and heuristic models. This holistic approach offers the following benefits:

  • Ensemble-Based Identification: By tapping into the unique strengths of individual models, Protecto ensures a wide coverage. The risk of errors arising from any single model's blind spots is minimized, resulting in a more robust prediction.
  • Contextual Understanding: NER brings to the table an understanding of context. This ensures precise identification of personal data entities, be it names, addresses, or identification numbers.
  • Structured Pattern Detection: The use of regex models means the tool is adept at spotting structured patterns, including phone numbers, email addresses, and date formats.

Measuring Effectiveness

How do we gauge the performance of such a tool? Precision, Recall, and F1-Score are the primary metrics used in the realm of data discovery and classification:

  • Precision (Accuracy): measures the proportion of named entities identified by the model that are actually correct. High precision indicates a low false positive rate. For instance, precision would indicate the proportion of data correctly identified as 'personal data' out of all the data that were labeled as 'personal data'. It's calculated as:
  • Recall: assesses how many of the actual named entities present in the dataset were correctly identified by the model. High recall means that the model correctly identifies most of the positive cases. Recall would indicate the proportion of actual personal data that were correctly identified out of all the actual personal data. High Recall means, most of the personal data were found, model didn't miss any personal data. Calculates as:
  • F1-Score: As with any classification problem, the F1-score for Named Entity Recognition models will provide a balance between precision and recall. Given that there's often a trade-off between the two, the F1 score is a crucial metric for many NLP tasks. An F1-Score closer to 1 indicates better performance, while closer to 0 indicates poorer performance. Calculated as:

Unrivalled Accuracy

Our customers can vouch for the superiority of our ensemble approach:

  • Protecto's data scanning technology has delivered a massive 98% accuracy rate in parsing and pinpointing personal data among our customer data. Industry benchmarks? BERT, renowned for its accuracy in various NLP tasks, holds an average accuracy of 89.5% on the GLUE benchmark. Meanwhile, Flair, another powerful NLP library, clocks in at 90.5% on the same benchmark.
  • When it comes to entity recognition tasks, our system, powered by our curated models, showcases an impressive F1 score of 94%. In comparison, BERT scores 92% on the GLUE benchmark for natural language understanding.


In an age where data breaches can spell disaster for businesses and individuals alike, tools like Protecto stand as guardians. By blending the capabilities of multiple models, we are not only ensuring comprehensive coverage but also setting new standards in accuracy and reliability. Protecto underscores the fact that when it comes to personal data protection, an ensemble-based approach is not just preferable; it's paramount.
