• How to download SAMPLE-AES-CTR encrypted stream

  28 décembre 2022, par Mqx

  When I open the mp4 file the audio works fine but the video is broken.


  


  This is the m3u8 file :

• Convert Webm to MP4 on the fly using ffmpeg for a Telegram bot using Typescript

  23 novembre 2022, par Hex

  I'm trying to make a very primitive telegram bot that get's a json and uploads the urls that are in the json to telegram.

  


  The problem is that there are urls that point to webm files I tried to see if there is a simple way to do this and I found this : https://www.npmjs.com/package/webm-to-mp4
but it doesn't seem to work sadly, it runs into this error : "

  I'm not sure what is causing it, my guess is that the webm-to.mp4 package was updated 2 years ago and something broke in the meantime.

  


  Is there a better way to do this then downloading the webm converting it and then sending it up to telegram ? If not how could I do the conversion using just ffmpeg ?

  


  Here is my current code :

  


  import { Telegram, MediaSource, HTML } from 'puregram'
import { HearManager } from '@puregram/hear'
import { createReadStream } from 'fs'
import postsJson from './posts.json';
const { promises: fs } = require("fs");
const webmToMp4 = require("webm-to-mp4");

const telegram = new Telegram({
  token: '********:AAEzriis6zNNjEQuw0BxF9M2RPA9V4lEqLA'
})
const hearManager = new HearManager()

telegram.updates.startPolling()
  .then(() => console.log(`started polling @${telegram.bot.username}`))
  .catch(console.error)

telegram.updates.on('message', hearManager.middleware)

var posts = postsJson;

telegram.updates.on('message', (context) => {
    posts.forEach( async data => {
      console.error(data.ext);
        if(data.ext == "jpg" || data.ext == "png"){
          context.sendPhoto(MediaSource.url(data.image), { caption: data.content  } );
          delay(1000);
        }
        if(data.ext == "gif"){
          context.sendAnimation(MediaSource.url(data.image), { caption: data.content  } );
          delay(1000);
        }
        if(data.ext == "webm"){
          //context.sendDocument(MediaSource.url(data.image), { caption: data.content  } );
          delay(1000);
        }
        delay(1000);
    })
})
fs.writeFile("file.mp4", Buffer.from(webmToMp4( fs.readFile("./file.webm"))));

function delay(ms: number) {
  return new Promise( resolve => setTimeout(resolve, ms) ); //This does not work either
}


  


  I wish everoyne a nice day !

  


• 4 Ways to Embed User Privacy & Data Security in Your Business

  15 juillet 2022, par Erin — Privacy

  Customer analytics undeniably plays a vital role for businesses. Product improvements, interface personalisation, content improvements, and creative advertising thrive on data. 

  Yet, there’s a fine line between being a customer-centred company and a privacy-violating one. 

  Due to ubiquitous online tracking, 62% of Americans now believe that it’s impossible to go about their daily lives without companies collecting data about them. Still, despite the importance of privacy in business for consumers, companies are reluctant to act. Privacy initiatives often stay on the back burner due to perceived complexity. That’s true to some extent.

  Privacy in business does assume complex technical changes to your data management. But to be a privacy-centred organisation, you also need to re-think your processes, practices, and culture. 

  Here are four ways to start your journey to better user privacy and data security. 

  1. Revise Your Data Collection Process to Gain Consumer Trust 

  The public is wary of sharing data with businesses because they are suspicious of its subsequent usage. 

  However, not all data collection is bad or wrong. In many cases, you need specific data for service delivery, compliance, or good-natured personalisation. 

  That’s exactly what consumers expect. Almost half of US consumers say they’d trust a company that limits the amount of personal information requested and only asks for data relevant to its products/services. 

  By limiting data collection and offering transparent data usage terms, you can : 

  • Reassure reluctant users to try your product or service — hence, boost conversions and sales. 
  • Retain existing audiences by gaining their trust, which leads to loyalty and higher customer lifetime value (CLV). 

  To gain consumers’ trust, implement proper consent and opt-out mechanisms. Then create educational materials about how you are collecting and using their data.

  2. Perform Data Mapping to Determine Where Sensitive Data Rests 

  Businesses are already pressed with an expanded cyber-security radar, courtesy of remote work, digital payment processing, IoT device adoption, etc. Yet, 41% of the executives don’t think their security initiatives have kept up with the digital transformations.

  Loopholes in security eventually result in a data breach. The average cost of a data breach looms at $4.24 million globally. The sum includes regulatory fines and containment costs, plus indirect losses in the form of reduced brand equity and market share. 

  Lax data protection in business also undermines consumer trust : 87% of consumers wouldn’t transact with a company if they had qualms with its security practices. 

  To improve your security posture, analyse where you are storing sensitive consumer data, who has access to it (internally and externally), and how you are protecting it. Then work with cybersecurity specialists on implementing stronger consumer security mechanisms (e.g. auto-log offs, secure password policy, etc) and extra internal security policies (if needed). 

  At the same time, start practising data minimisation. Ensure that all collected data is : 

  • Adequate – sufficient to meet your stated objectives 
  • Relevant – is rationally linked to the objectives 
  • Limited – no unnecessary data is collected or stored
  • Timely – data is periodically reviewed and removed when unnecessary 

  

  These principles prevent data hoarding. Also, they help improve your security posture and regulatory compliance by reducing the volume of information you need to safeguard.

  3. Do an Inventory of Your Business Tools

  Data leaks and consumer privacy breaches often occur through third parties. Because Google Analytics was deemed in breach of European GDPR in France, Austria and Italy, businesses using it are vulnerable to lawsuits (which are already happening). 

  Investigate your corporate toolkit to determine “weak links” – tools with controversial privacy policies, murky data collection practices, and poor security. 

  Treat it as a journey and pick your battles. By relying on Big Tech products for years, you might have overlooked better alternatives. 

  For example :

  • Matomo is a privacy-centred Google Analytics alternative. Our web analytics is compliant with GDPR, CCPA, and other global privacy laws. Unlike Google Analytics, we don’t exploit any data you collect and provide full transparency into how and where it’s stored. Or if you want a simple analytics solution, Fathom is another great privacy-friendly option.

  

  • For online data storage, you can choose Proton Drive or Nextcloud (open-source). Or host your corporate data with a local cloud hosting provider to avoid cross-border data transfers.

  

  Aim to progressively replace Google products with more privacy-centred alternatives. 

  4. Cultivate a Privacy-Centred Corporate Culture 

  To make privacy a competitive advantage, you need every team member (at every level) to respect its importance. 

  This is a continuous process of inspiring and educating your people. Find “privacy ambassadors” who are willing to lead the conversations, educate others, and provide resources for leading the change. 

  On an operational level, incorporate privacy principles around data minimisation, bounded collection, and usage into your Code of Conduct, standard operating procedures (SOPs), and other policies. 

  Creating a privacy-centric culture takes effort, but it pays off well. Cisco estimates that for each dollar spent on privacy, an average organisation gets $2.70 in associated benefits. Almost half (47%) of organisations gain 2X returns on their privacy initiatives.

  Moving Forward with a Data Privacy Programme 

  Privacy has become a strong differentiator for brands. Consumers crave transparency and ethical data usage. Regulators mandate limited data collection and proper security mechanisms.

  But sweeping changes are hard to implement. So start small and go one step at a time. Understand which first-party data your company collects and how it is stored.

  Then look into the tools and technologies you are using for data collection. Do these provide sufficient privacy controls ? How are they using data collected on your behalf ? Finally, move to wider transformations, pertaining to data management, cybersecurity, and cultural practices. 

  Be consistent with your effort — and eventually, all the pieces will fall into place.
