Deduplication
Data Deduplication
Identifying and eliminating duplicate copies of data to reduce storage requirements and improve efficiency.
Technical Detail
Deduplication is a common concept in file processing and digital tool workflows. Browser-based implementations use Web APIs (File API, Canvas, Web Workers) to process data entirely on the client device. This architecture eliminates server-side dependencies, reduces latency to near-zero for processing tasks, and ensures complete data privacy since files never leave the browser's sandbox. The primary constraint is browser memory — large files may require streaming or chunked processing approaches.
Example
```javascript
// Deduplication: file processing example
const file = document.getElementById('fileInput').files[0];
const reader = new FileReader();
reader.onload = (e) => {
const data = e.target.result;
console.log(`Loaded: ${file.name} (${file.size} bytes)`);
};
reader.readAsArrayBuffer(file);
```
