Big Data & Data Governance 

Big Data sets are characterized by the exponential development in the volume, speed and variety of data that can be processed and exploited. The phenomenon, still poorly described, is based on technological innovations that overlap (development of the Internet, artificial intelligence, cloud computing, hybrid supercomputers, distributed file systems, etc.) and which as a result constantly increase the volume of data available. The benefits and economic spinoffs are particularly important in this revolutionary digital age.

Building a Big Data project involves taking into account a complex environment, both in technical and legal terms. The reason is that these projects must take into account highly diverse issues (cyber-security, data protection, competition law, intellectual property, database law, etc.).

DEROULEZ AVOCAT supports its customers in implementing the following tools:

  • Analysis and the general legal framework of a data project;

  • Legal aspects of the data life cycle;

  • Implementing a policy applied to data;

  • The legal issues of data storage, security and retention;

  • The conditions for managing and sharing data (particularly in the context of databases);

  • Legal issues related to the architecture and processes of information systems [implementation of master data management (MDM) etc.]

  • Setting up data governance.

    The firm is also involved in monitoring and tracing legislation and regulations in France and Europe in these areas. 

The expertise of the DEROULEZ AVOCAT Law firm

While the increases in volumes of data exchanges are unprecedented, information law is under construction and is a cross-cutting issue requiring a combination of skills (public law, literary and artistic property, European law, private international law, etc.). 

As such, the firm has developed specific expertise thanks to its participation in numerous academic studies in this field or as part of monitoring the "data" projects of its clients.
