Can one read a sealed letter without opening it?

Discover how a new technology developed by MIT allows reading the contents of sealed letters without ever opening them physically.

Through the use of X-ray microtomography and a sophisticated algorithm, this innovation opens the door to uncovering secrets buried in ancient correspondence.

"Letterlocking" was common in ancient times for securing communications. This technique of physically locking letters through folding and sealing was widespread in Europe since the 13th century. Today, MIT is revolutionizing this practice by enabling virtual reading of sealed letters.

The magic of microtomography

Advanced imaging: Digitization, Resolution, Volume, Technology, Scan

Using state-of-the-art machines used in dental medicine, MIT was able to perform scans with extraordinary resolution. These high-definition images were then analyzed by a specialized algorithm to reconstruct the contents of the letters, layer by layer, without ever physically touching them.

A revolutionary algorithm

The algorithm developed by Amanda Ghassaei and Holly Jackson has been the main driving force behind this technological feat. Based on in-depth analysis of thousands of letters, this algorithm succeeded in separating the thinnest paper layers, thus revealing the hidden contents of sealed correspondence.

Letters as witnesses to History

These sealed letters are not just ancient documents but true witnesses of history. They offer a valuable glimpse into daily life across different eras and for individuals from all social backgrounds. Thanks to this technology, we can now uncover the secrets buried within these time capsules.

The technology developed by MIT opens exciting new possibilities for historians and researchers worldwide. It seems that even the best-kept secrets can be revealed through human ingenuity and advances in modern technology.
