Documentorum

Documentorum is a global initiative and a new approach to issuing, registering and validating certificates and diplomas. It has been developed with the use of Hyperledger technology. It enables students to collect all their academic credentials in one place where they are protected against theft and fraud.

Educational institutions can minimize their costs by using Documentorum for issuing, storing and validating diplomas and certificates. The blockchain technology applied guarantees forgery protection. Documentorum can also come in handy to employers, as it makes pre-employment document check easy and short-length. Above that, it provides the information about candidates’ competences and skills.

Challenge

The Exelor team faced a complex task to develop a business solution for creating, storing and validating documents in a convenient and secure way. The technology to choose had to protect the documents against accidental editing or deleting. With paid access to the database, Documentorum had to support instant validation and authentication of the documents.

It was crucial that the mobile application version of Documentorum could keep all the functionality of the platform.

Solution

The team has implemented the following solutions:

  • the blockchain technology Hyperledger that makes storage of documents safe and well protected;
  • the editor which helps to create templates of certificates (graphic module);
  • the mobile application Dart + Flutter SDK which was developed to make it possible to operate your account 24/7;
  • document authentication that is run by scanning the QR code from the Documentorum mobile application;
  • access to the database that depends on the pre-chosen access rights.

Result

The users’s digital academic credentials stay perfectly safe as they cannot be deleted or falsified once they are in Documentorum. Besides, they include detailed information about the curriculum and the students’ progress. Documentorum significantly reduces the costs associated with issuing, storing and validating credentials offering a higher level of security and confidentiality in comparison to conventional methods.

Where I Am

WhereIAm is a cross-platform mobile application for fixing the position of another user’s smartphone. The key feature of the application is that location tracking is activated only upon request. This significantly reduces the load on the phone’s battery and thereby qualitatively distinguishes WhereIAm from its competitors.

Challenge

The challenge was to create a mobile application for fixing the geolocation of other smartphone users, qualitatively different from its competitors in the following characteristics:

  • free to use;
  • lightweight;
  • energy efficient;
  • high accuracy of geo-positioning;
  • parental control option;
  • real-time geo-positioning option.

Solution

Having assessed the client’s requirements, the New Line Technologies team decided to implement this project using the Flutter framework and the Google Firebase platform. This made it possible to avoid writing separate source code for Android and iOS and thereby significantly reduce development costs, and Firebase provided automatic scalability of the application in the future.

  • WhereIAm is less than 34 MB, which is significantly less compared to some popular analogs.
  • The application has a simple and intuitive interface. To launch it, perform only two actions: generate and enter a code for binding smartphones.
  • To prevent possible violations of human rights, the application has an authorization system that allows tracking only after user approval. Thus, two-way location sharing requires the consent of both parties.
  • Available parental control allows parents to unilaterally get the child’s geolocation.
  • Additional functionality for employees is in the process of implementing. It will allow setting working hours and working days for each user, tracking his location during the working time. This solution will reduce the time needed to search for a person in the office. Also, a beacon-device integration will be developed that will help determine the exact room in the office where the person is located.

Result

On the one hand, location tracking applications are quite useful for caring for loved ones and children. While on the other, they can be used for unlawful purposes. The New Line Technologies team is pleased to provide in the WhereIAm application an opportunity for caring for loved ones, as well as programmatically implement tracking protection without prior consent from the user.
