+      subtitle: 'December 2023'
+      text: |
+        This dataset comes from our mobile GPU-based eavesdropping work, [Eavesdropping user credentials via GPU side channels on smartphones](/publication/2022-mobile-gpu-eavesdropping/), presented at the 27th ACM International Conference on Architectural Support for Programming Languages and Operating Systems (ASPLOS 2022). It contains 3,466 traces of mapping between the on-screen keyboard key presses and corresponding Snapdragon Adreno GPU performance counter changes collected on device in the meantime.
+        ## Dataset Structure
+        The dataset is arranged in the following format:
+        * Folder name (e.g., `1622457056`): This UNIX timestamp when the experiment took place.
+            * `timestamp_data.csv`: Raw recording of GPU performance counter changes during the experiment.
+                * Column 1: UNIX timestamp of each performance counter ("PC") value change event, with granularity of 1 microseconds.
+                * Column 2-13: GPU PC value changes of different types:
+                    * `PERF_LRZ_VISIBLE_PRIM_AFTER_LRZ`
+                    * `PERF_LRZ_FULL_8X8_TILES`
+                    * `PERF_LRZ_PARTIAL_8X8_TILES`
+                    * `PERF_LRZ_VISIBLE_PIXEL_AFTER_LRZ`
+                    * `PERF_RAS_SUPERTILE_ACTIVE_CYCLES`
+                    * `PERF_RAS_SUPER_TILES`
+                    * `PERF_RAS_8X4_TILES`
+                    * `PERF_RAS_FULLY_COVERED_8X4_TILES`
+                    * `PERF_VPC_PC_PRIMITIVES`
+                    * `PERF_VPC_SP_COMPONENTS`
+                    * `PERF_VPC_LRZ_ASSIGN_PRIMITIVES`
+                    * `PERF_VPC_SP_LM_COMPONENTS`
+            * `timestamp_keys.csv`: Keyboard key presses occurred during the experiment.
+                * Column 1: UNIX timestamp of each key press, with granularity of 1 microseconds.
+                * Column 2: The specific key press occurred.
