The EDW^® platform leads the industry in handwriting interpretation accuracy. Our proprietary techniques combine and improve upon the results from best-of-breed commercially available interpretation engines. Additionally, a growing set of custom datatypes guides and optimizes the interpretation. By combining the best commercial engines with our proprietary techniques, the EDW platform achieves a more accurate handwriting interpretation than other industry products.

The EDW platform also employs common and customer-specific lexicons, to which new entries are automatically added during the verification of the interpretation. Common lexicons contain information of value to multiple customers such as city names and first and last names. Customer-specific lexicons contain information unique to the customer such as product or parts list, office names, and employee identification numbers. Since lexicons can be updated during verification, the platform’s handwriting interpretation improves over time. Our advanced proprietary techniques also interpret graphical images, converting marks on a graphic image to numerical values. For instance, a person might be asked to make a mark on a scale to indicate their agreement with a specific statement. The EDW platform converts the mark made by the user into a numerical value that can be sent to a back-end system for statistical reporting and analysis.

ExpeData has a demonstrated and proven commitment to security. We understand that securing data is of the utmost importance to your business; therefore ensuring that data is protected is our highest priority. Our market-leading EDW^® solutions ensure that your data is protected at every stage of the digital writing process – from information acquisition and transmission to data processing and storage.

ExpeData's EDW platform offers a comprehensive and configurable set of security features. Our EDW platform¹ is built on a multi-level firewall-protected system complete with host intrusion detection and monitoring, hardware and software monitoring, disaster recovery and data backup mechanisms including offsite tape storage. All data transmitted to and from the EDW platform is encrypted with 128 bit SSL and is password protected. The EDW system provides options for different levels of encryption between clients and servers, and stroke transmission can be configured to require authentication. Data is backed up frequently to ensure that it is protected and accessible. The EDW platform is also flexible in that it can be fully embedded and hosted within the customer's own IT system infrastructure, utilizing existing corporate security policies. 

We employ security measures throughout the process including restricted access and user right privileges. The EDW platform uses a role-based model for assigning access. Each role defines the parts of the EDW platform to which a user will be allowed access. No single role has complete authority by default, and users cannot assign their own roles. A user's logins are monitored to detect unauthorized intrusions. The ExpeData software features multi-level password protection from user to administrative levels, restricting access to captured data and images.  Audit logs are stored in a database for all actions performed by users on clients and servers, and an audit log entry is triggered whenever any data is changed.  Audit trails can be viewed for users, pens, and groups.

ExpeData's EDW platform has been validated by an independent third party and found to meet the required security components of the United States Food and Drug Administration (FDA) 21 Code of Federal Regulations (CFR) Part 11. Part 11, as it is commonly called, deals with FDA regulations on electronic records and electronic signatures in the United States. This code defines the criteria under which electronic records and electronic signatures are considered to be trustworthy, reliable and generally equivalent to paper records. These security features and requirements are applicable to all industries concerned about authenticity and confidentiality of electronic information.

The EDW^® Server has a range of configurability options. It is composed of components and modules that can be set up as single-server or multi-machine configurations. It can even run on an individual laptop for demonstration and development purposes.

The platform is also offered as a service hosted at ExpeData. In this case, strokes are directed to load-balanced servers at ExpeData for processing, and the resulting data is then securely provided to the customer via FTP, e-mail or direct Web service interaction.

The EDW platform supports input from the digital pen through a USB connection to a PC, or via Bluetooth^®-enabled mobile devices. ExpeData supports communication devices from many different manufacturers as well as RIM and Microsoft Mobile devices.

The EDW platform also accepts input of varied information through its secure Web service API.

The EDW^® Server produces output in industry standard formats, making it compatible with back-end systems across the enterprise. Interpreted data output is produced in XML format, using form and field names specified by the user. Page image output is produced in PDF, TIF, GIF, PNG, or JPG formats and is available in user specified image resolutions.

For easy maintenance, server-related warning conditions are noted in logs and generate e-mail or SMS notifications. The platform can be successfully maintained through remote access. If desired, ExpeData Customer Support can remotely access a customer’s server to assist with any problems. Forms, users, digital pens, and additional information can be managed remotely through the Web-based Admin Interface program.

The EDW platform is currently capable of interpreting forms written in English, French, Spanish, and Portuguese, and is extensible to other languages. Additionally, the platform is localized for specific geographic regions to ensure highly accurate handwriting interpretation. For example, the English language system is localized for the United States, South Africa, and Australia, and the Portuguese system is localized for Portugal and Brazil.
