1 00:00:00,050 --> 00:00:03,200 Lessen privacy preserving machine learning techniques. 2 00:00:03,230 --> 00:00:09,020 Privacy preserving machine learning techniques are essential in the development and testing phases of 3 00:00:09,020 --> 00:00:11,030 the AI development lifecycle. 4 00:00:11,840 --> 00:00:17,690 These techniques ensure the safeguarding of sensitive information while maintaining the efficacy and 5 00:00:17,690 --> 00:00:20,060 accuracy of machine learning models. 6 00:00:20,930 --> 00:00:26,660 Privacy concerns have become increasingly significant as machine learning models are often trained on 7 00:00:26,660 --> 00:00:30,770 large data sets that include personal and sensitive information. 8 00:00:30,800 --> 00:00:36,860 Implementing robust privacy preserving methodologies is not only a regulatory requirement, but also 9 00:00:36,860 --> 00:00:39,980 a critical component of ethical AI development. 10 00:00:41,300 --> 00:00:46,460 One prominent technique in privacy preserving machine learning is differential privacy. 11 00:00:46,790 --> 00:00:52,820 Differential privacy provides a mathematical framework for quantifying and limiting the risk of exposing 12 00:00:52,820 --> 00:00:55,250 individual data entries in a dataset. 13 00:00:55,880 --> 00:01:01,850 This technique introduces random noise to the data or the results of data queries, ensuring that the 14 00:01:01,850 --> 00:01:07,790 inclusion or exclusion of a single data point does not significantly affect the outcome. 15 00:01:07,790 --> 00:01:12,740 This makes it difficult for adversaries to infer specific information about individuals. 16 00:01:12,770 --> 00:01:19,400 Google has notably employed differential privacy in its data analytics tools, balancing user data utility 17 00:01:19,400 --> 00:01:20,420 and privacy. 18 00:01:21,020 --> 00:01:26,810 A study by Erlingsson, Pehr, and Koroleva demonstrated the effectiveness of differential privacy in 19 00:01:26,810 --> 00:01:32,060 large scale systems, highlighting its practical applicability in real world scenarios. 20 00:01:33,440 --> 00:01:38,720 Another critical approach is federated learning, which allows machine learning models to be trained 21 00:01:38,720 --> 00:01:44,030 across multiple decentralized devices or servers while keeping the data localized. 22 00:01:44,540 --> 00:01:50,150 This method ensures that raw data never leaves the user's device, significantly reducing the risk of 23 00:01:50,150 --> 00:01:51,200 data breaches. 24 00:01:51,830 --> 00:01:58,190 Federated learning aggregates model updates rather than raw data, enhancing privacy and security. 25 00:01:58,220 --> 00:02:03,920 Google has successfully implemented Federated Learning in its Gboard keyboard application, enabling 26 00:02:03,920 --> 00:02:07,910 predictive text functionalities without compromising user privacy. 27 00:02:08,480 --> 00:02:14,280 This approach not only improves privacy, but also leverages the computational power of edge devices, 28 00:02:14,280 --> 00:02:17,850 making it a scalable solution for various applications. 29 00:02:19,410 --> 00:02:25,470 Homomorphic encryption is a cryptographic technique that allows computations to be performed on encrypted 30 00:02:25,470 --> 00:02:27,510 data without decrypting it. 31 00:02:27,840 --> 00:02:32,940 This ensures that sensitive data remains secure even during the processing stages. 32 00:02:33,480 --> 00:02:39,270 Homomorphic encryption can be particularly useful in scenarios where data needs to be processed by third 33 00:02:39,270 --> 00:02:40,560 party services. 34 00:02:40,740 --> 00:02:46,200 Although historically computationally intensive, advancements in this field have made it more feasible 35 00:02:46,200 --> 00:02:48,090 for practical applications. 36 00:02:48,930 --> 00:02:54,930 For instance, Microsoft's Seal provides tools for homomorphic encryption, enabling privacy preserving 37 00:02:54,930 --> 00:02:57,330 computations in cloud environments. 38 00:02:57,900 --> 00:03:02,820 The use of homomorphic encryption in machine learning models ensures that data privacy is maintained 39 00:03:02,820 --> 00:03:05,580 throughout the model training and inference processes. 40 00:03:08,280 --> 00:03:14,170 Secure multi-party computation is another method that allows multiple parties to collaboratively compute 41 00:03:14,200 --> 00:03:17,830 a function over their inputs while keeping those inputs private. 42 00:03:18,400 --> 00:03:24,910 Smpc enables joint data analysis without exposing the underlying data to any party involved. 43 00:03:25,480 --> 00:03:30,490 This is particularly useful in scenarios where data from different sources needs to be combined for 44 00:03:30,520 --> 00:03:32,020 machine learning purposes. 45 00:03:32,650 --> 00:03:39,430 A notable example of smpc in practice is its use in genomic research, where data from multiple institutions 46 00:03:39,430 --> 00:03:43,180 can be analyzed without compromising patient confidentiality. 47 00:03:43,450 --> 00:03:49,600 Smpc ensures that collaborative efforts in data analysis can be achieved without sacrificing privacy, 48 00:03:49,600 --> 00:03:54,010 making it a valuable tool in the development and testing phases of machine learning models. 49 00:03:56,830 --> 00:04:02,350 Lastly, the concept of privacy preserving generative adversarial networks has gained attention. 50 00:04:02,920 --> 00:04:08,830 Gans can generate synthetic data that mimics the statistical properties of real data without revealing 51 00:04:08,830 --> 00:04:10,180 sensitive information. 52 00:04:11,080 --> 00:04:16,570 This synthetic data can be used to train machine learning models, reducing the dependency on actual 53 00:04:16,570 --> 00:04:17,710 sensitive data. 54 00:04:17,760 --> 00:04:23,730 Privacy preserving Gans incorporate mechanisms to ensure that the generated data does not inadvertently 55 00:04:23,730 --> 00:04:25,320 leak private information. 56 00:04:25,950 --> 00:04:27,420 Research by Shi et al. 57 00:04:27,450 --> 00:04:33,750 Demonstrates the potential of Gans in generating high quality synthetic data while preserving privacy, 58 00:04:33,780 --> 00:04:37,890 providing a viable solution for data augmentation and model training. 59 00:04:39,060 --> 00:04:45,300 The integration of privacy preserving techniques in the AI development life cycle is critical for ensuring 60 00:04:45,300 --> 00:04:51,030 that machine learning models can be developed and tested without compromising user privacy. 61 00:04:51,660 --> 00:04:57,690 These techniques not only address regulatory requirements, but also build trust with users and stakeholders. 62 00:04:58,290 --> 00:05:03,750 As machine learning applications continue to grow, the importance of privacy preserving methodologies 63 00:05:03,750 --> 00:05:08,880 will only increase, necessitating ongoing research and development in this field. 64 00:05:10,020 --> 00:05:15,210 The implementation of these privacy preserving techniques requires a deep understanding of both the 65 00:05:15,210 --> 00:05:18,570 theoretical foundations and practical implications. 66 00:05:19,500 --> 00:05:20,820 Differential privacy. 67 00:05:20,850 --> 00:05:22,170 Federated learning. 68 00:05:22,190 --> 00:05:27,740 Homomorphic encryption, secure multi-party computation, and privacy preserving Gans. 69 00:05:27,740 --> 00:05:30,890 Each present unique challenges and opportunities. 70 00:05:31,370 --> 00:05:37,250 For instance, the balance between privacy and utility is a common theme across these techniques, requiring 71 00:05:37,250 --> 00:05:39,050 careful calibration and tuning. 72 00:05:39,080 --> 00:05:44,600 Additionally, computational overhead and scalability are practical considerations that must be addressed 73 00:05:44,630 --> 00:05:48,650 to ensure the feasibility of these techniques in real world applications. 74 00:05:51,170 --> 00:05:56,990 In conclusion, privacy preserving machine learning techniques are indispensable in the AI development, 75 00:05:56,990 --> 00:05:59,600 life cycles, development, and testing phases. 76 00:06:00,020 --> 00:06:06,260 They provide robust mechanisms to protect sensitive information while enabling the creation of effective 77 00:06:06,260 --> 00:06:08,570 and accurate machine learning models. 78 00:06:09,050 --> 00:06:14,930 As the field of AI continues to evolve, the integration of these techniques will be paramount to ensuring 79 00:06:14,930 --> 00:06:17,330 ethical and secure AI systems. 80 00:06:17,990 --> 00:06:23,510 Continued advancements and innovations in privacy preserving methodologies will play a crucial role 81 00:06:23,510 --> 00:06:26,450 in the responsible development of AI technologies.
