Businesses worldwide use document upload apps to upload, store, manage, and share documents. These documents can contain sensitive business, customer, employee, and partner data. A single data breach in such apps can cost organizations millions.
Microsoft’s 2024 data breach report shows that the average global cost of a data breach has reached USD 4.88 M. Regular document upload apps are at a high risk of cyber-attacks and data breaches. Therefore, using secure document upload apps is crucial for organizations. It helps them comply with regulations and prevent data breaches.
In this article, we’ll discuss the differences between secure vs. regular document upload apps. We’ll also discuss how the Filestack file uploading service ensures secure document uploads with advanced security features.
Key takeaways
- Regular document upload apps offer basic file-uploading features. They usually lack the security features required to protect sensitive data.

What are regular document upload apps?
Document upload apps allow users to upload, store, organize, and share different types of documents. These include PDFs, MS Word Docx, Excel sheets, and more. Some apps have basic file-uploading capabilities, while others offer advanced features like drag-and-drop, file previews, file validation, and OCR.
Here are some examples of document upload apps:
- Cloud storage platforms that provide file upload, storage, and sharing capabilities.
- Job portals that allow users to upload resumes or supporting documents.
- Plugins used in web apps to enable users to upload and download files.
Regular document upload apps lack advanced security features. Thus, they are prone to cyber-attacks and data breaches.
What makes document upload apps secure?
Secure document upload apps implement advanced security features to protect highly sensitive data. These apps are crucial for organizations or industries that deal with confidential user data. They help comply with regulations and prevent data breaches.
Here are key security features of secure document upload apps:
Encryption
Encryption is one of the most common and effective methods to protect sensitive data. It involves protecting data using a specific algorithm and an encryption key. Recipients can access this data using a decryption key. Unencrypted files are more vulnerable to data breaches.
There are different types of encryption, such as:
- In-Transit EncryptionIt helps protect private data during the upload process using protocols like HTTPS and TLS.
- At-Rest EncryptionThis type of encryption protects uploaded files stored on servers. AES-256 encryption is most commonly used to protect data at rest.
- End-to-End Encryption (E2EE)E2EE is crucial for secure file sharing. It encrypts sensitive documents on the sender’s device. These files are only decrypted on the recipient’s device. This way, E2EE ensures that only the intended recipient can access or read the data. E2EE protects from eavesdropping. Even service providers cannot read or intercept the encrypted data.
Authentication
Authentication is another effective method to protect uploaded files from unauthorized parties. It helps verify user identities and restrict access to sensitive files. Multi-factor authentication (MFA) is one of the most effective methods to prevent unauthorized access. It requires users to verify their identity using two or more factors before providing access to the document upload app.
File upload APIs also use API keys to authenticate and authorize access to APIs.
Role-Based Access Control (RBAC)
RBAC helps restrict who can upload, download, or view files. It involves assigning permissions to users depending on their roles within the organization. Roles are created based on the specific tasks and responsibilities associated with them, such as “Admin,” “Manager,” and “Employee”. Access to resources is provided and restricted according to assigned roles.
File Type Validation
File type validation is another crucial security feature of secure document upload apps. It prevents cybercriminals from uploading malicious files containing executable scripts. These files can compromise the app when they are downloaded and opened.
File type validation also helps check the compatibility of uploaded files with the app’s functionalities.
Comparing Secure vs. Regular Document Upload Apps
Secure file-sharing platforms and document upload apps implement strong security measures that regular document upload apps often lack. For example, secure apps implement MFA, Single Sign-On (SSO), advanced encryption mechanisms, and RBAC. Regular apps, on the other hand, use basic username and password authentication. They also support limited access control mechanisms.
Secure document upload apps ensure better data protection and compliance. In contrast, regular document upload apps are at a higher risk of data breaches.
The table below shows a quick comparison of secure vs. regular document upload apps:
Secure document upload apps | Regular document upload apps | |
Authentication | Implements MFA, SSO, and hashed passwords | Uses basic username and password |
Access Control Mechanism |

const filestackClient = filestack.init('YOUR_API_KEY'); // Replace 'YOUR_API_KEY' with your actual Filestack API key.
const uploadButton = document.getElementById('upload-button');
const fileList = document.getElementById('file-list');
const previewContainer = document.getElementById('preview-container');
uploadButton.addEventListener('click', () => {
filestackClient.picker({
maxFiles: 5, // Allow up to 5 files
accept: 'application/*', // Accept all document types
onUploadDone: (result) => {
fileList.innerHTML = ''; // Clear the file list before showing new files
previewContainer.innerHTML = ''; // Clear previous previews
result.filesUploaded.forEach(file => {
// Display file name
const fileNameElement = document.createElement('div');
fileNameElement.classList.add('file-name');
fileNameElement.innerText = file.filename;
fileList.appendChild(fileNameElement);
// Add preview iframe
const iframe = document.createElement('iframe');
iframe.src = file.url;
previewContainer.appendChild(iframe);
});
// Success message
const successMessage = document.createElement('div');
successMessage.classList.add('success-message');
successMessage.innerText = 'Files uploaded successfully!';
fileList.appendChild(successMessage);
}
}).open();
});
</script>
</body>
</html>
Output
When you click the upload button, it’ll open the Filestack File Uploader:
You can also upload multiple files through the uploader:
Implementing policies and signature
Filestack doesn’t require policies and signatures for file uploads by default, but you can still implement these parameters to enhance the security of your uploads. You must generate policies and signatures on the server side to keep your security secret safe.
Here’s a simple code for generating policy and signature in Node.js:
const crypto = require('crypto');
const express = require('express');
const app = express();
const API_KEY = 'your_filestack_api_key';
const SECURITY_SECRET = 'your_filestack_security_secret';
app.use(express.json());
// Generate Policy and Signature
app.get('/getPolicyAndSignature', (req, res) => {
const policy = {
expiry: Math.floor(Date.now() / 1000) + 3600, // Policy expires in 1 hour
call: ['pick', 'read', 'store', 'write'], // Allowed actions
handle: '*', // Allow access to all files
};
const policyString = Buffer.from(JSON.stringify(policy)).toString('base64');
const signature = crypto.createHmac('sha256', SECURITY_SECRET).update(policyString).digest('hex');
res.json({ policy: policyString, signature: signature });
});
// Start the server
const PORT = 3000;
app.listen(PORT, () => console.log(`Server running on port ${PORT}`));
Here’s how you can fetch policy and signature from the server:
const response = await
fetch('http://localhost:3000/getPolicyAndSignature');
const { policy, signature } = await response.json();
// Set security options
const security = {
policy,
signature,
